Cimetrix Book Club: "Agile Testing: A Practical Guide for Testers and Agile Teams" by Lisa Crispin and Janet Gregory

Posted by Morgan Kap; QE Engineer on Jun 5, 2019 10:30:00 AM

Cimetrix-book-club-1Today we are introducing the Cimetrix Book Club on our blog. Our employees are always striving to develop their skills, share information, and keep up to date with the industry. Part of this effort includes an employee book club that involves many of our team members each month. We will cover some of their favorites from time-to-time here on our blog!

Today's book is called "Agile Testing: A Practical Guide for Testers and Agile Teams" by Lisa Crispin and Janet Gregory, two of the industry’s most experienced agile testing practitioners and consultants. The book review is by Morgan Kap, a QE Engineer based in Salt Lake City, UT, USA.Agile-testing-bookclub-1This book on agile testing is a great high-level explanation of how testing fits into an agile development team. The focus of this book is on how to successfully transition a team to an agile methodology, or to create a new QE/testing team in an agile methodology. While our team was already practicing agile before we read the book, it had quite a bit of valuable knowledge that led our team to make changes in how we tackle daily testing tasks.

One of the main changes we made immediately was to slightly restructure our team, and we have become a more effective team as a result. This book on Agile Testing is full of real-world stories of testing success and failures. These stories show the importance of techniques and tools, outlined for easy understanding in the book, for developing an efficient and complete testing process.

Some of the major focus points include being test driven during development and the many benefits this can create for all types of projects. Another focus details the many ways a software product should be tested; from security to usability. There is even a chapter focusing on how an office’s culture can have an impact on testing. This topic led to our team to try a few new things to make our culture more fun and interesting. This now includes having rubber ducks on every desk - that's a long-story, but we love it.

Overall, "Agile Testing: A Practical Guide for Testers and Agile Teams" by Lisa Crispin and Janet Gregory, is a great starting point for those quality engineering teams that searching for ideas and way to improve and understand many of the important aspects of testing software.

Cimetrix had a great showing at SEMICON Southeast Asia!

SEMICON-SEA-Asia-2018Cimetrix just finished exhibiting at SEMICON Southeast Asia for the first time. And a grand entrance it was. Located in Kuala Lumpur, Malaysia, this is one of the regional SEMICON shows put on by SEMI, a global industry association serving the manufacturing supply chain for the electronics industry. Southeast Asia is a hotbed for semiconductor backend and PCBA (SMT) industries. With our new employee Raymund Yeoh located in Penang, Malaysia; combined with our distribution partner Electrotek based out of Singapore, Cimetrix now has a strong presence to support Industry 4.0 adoption in Southeast Asia. 

semicon-sea-post-1-1By working closely with SEMI, Cimetrix had a new booth in the SEMI Smart Manufacturing Pavilion and an impressive demonstration in the SEMI Smart Manufacturing Journey.

Our new booth emphasized (1) our global reach as the world’s largest supplier of equipment connectivity and control software, (2) our new SapienceTM factory side platform which has beta installations at select major EMS and electronics manufacturing sites, and (3) our new EquipmentTestTM connectivity tester designed to make equipment connectivity easier than ever before.

booth-semi-sea-1Our booth was extremely busy the whole time with demonstrations of Sapience and EquipmentTest. We gave out vouchers for free copies of EquipmentTest to booth visitors which generated excitement and will increase learning for GEM connectivity in Southeast Asia. It was interesting to see the number of factory engineers and managers who visited us seeking help with getting their equipment connected for traceability and OEE (Overall Equipment Effectiveness). And we had the answers. Right next door to our booth was the SEMI Smart Manufacturing Journey which had guided tours demonstrating the use of Industry 4.0 throughout the electronics manufacturing supply chain. Our job was to demonstrate data collection using standards from live equipment in real time displaying OEE charts and data for each tour to witness. Setting this up can take months in a factory. Our Smart Factory Business Team is out to turn this problem upside down. They connected to all 4 live equipment in one day and were ready to go at the start of the show. And we are ready to do that in factories too. 

mike-semi-sea-tourHere is Mike and Jesse giving a demonstration to a tour group. The equipment is located right behind the crowd for all to see; with Sapience displaying data and the crowd taking pictures. SEMI did a great job organizing this. We had top government officials, factories, equipment manufacturers, electronics distributors and universities come through the tours. We also exceeded expectations by adding artificial intelligence to the demonstration. Amazon Alexa was integrated into Sapience which allowed us to ask Alexa which factory was most productive last week. Alexa and Sapience analyzed the data and gave the answer to the tour crowd.

We have many new opportunities to follow up; and we will be working with SEMI on how to help companies in Southeast Asia learn and adopt Industry 4.0.

Following the show, our team spread out to visit the rapidly growing Cimetrix customer base in Penang, Korea, India and China with support from our local teams. See you next year in SEMICON Southeast Asia!

Do you need help with GEM Testing?

Posted by David Francis: Director of Product Management on May 22, 2019 11:21:00 AM

A few years ago, I went through the process of building a new house. It was exciting to work with the architect to design the house and imagine what the finished product was going to be like. The architect created a 40-page set of drawings detailing all the components that would go into the house, like the electrical, plumbing and flooring. I thought everything was covered. I was a little surprised when things didn’t go exactly as detailed in the drawings. There were exceptions! However, having the detailed drawings made it easier to identify where things went wrong and helped clarify what needed to be done to correct the problems.EquipmentTest-Software-Control

Communication standards like GEM are like a set of architectural drawings for how to connect equipment to factory control systems. They define what needs to be communicated, how the communication needs to take place and provide a great roadmap for getting there. But like building a new house, there are usually a few surprises along the way. A standard, consistent way of testing the interface that can be used by both the factory and equipment manufacturer, greatly reduces the unknown and simplifies the process.

The new Cimetrix EquipmentTest™ product is the fastest way to achieve GEM Compliance for factory acceptance testing of new equipment. Whether you are an equipment manufacturer or factory, making sure the equipment interface is GEM compliant is critical. Having an easy-to-use testing solution to determine if the equipment is GEM compliant is critical.

There are two versions of EquipmentTest depending on your needs. The EqupmentTest Basic version is ideal for both Smart factories and equipment manufacturers to quickly and easily test the basic capabilities of an equipment’s GEM interface. EquipmentTest Basic includes a simple testing scenario, called a plugin, to evaluate the equipment’s ability to connect to a GEM host and communicate events, data and alarms. This version also includes the ability to send/receive individual messages to/from the equipment for discovery or diagnostic purposes. With the messaging functionality, you can also create macros to send and receive groups of messages.

For more complex testing, there is the EquipmentTest Pro version. In addition to all the features of the EquipmentTest Basic version, EquipmentTest Pro includes a full, rigorous GEM compliance testing plug-in and an operational GEM compliance testing plugin. The Pro version includes development tools to allow you to create your own custom tests/plug-ins using .NET languages. The GEM compliance plugin generates a GEM compliance statement that shows the areas and level of compliance to the GEM standards. There are also other tools only available in the EquipmentTest Pro version that allow you easily test and interact with the GEM functionality on the equipment.

As with all our products, Cimetrix supports the industry connectivity standards so you never have to wonder if your equipment is keeping up with the rest of the industry.

You can purchase either version of EquipmentTest directly from our website and download the software immediately. You will need to provide a valid Mac ID and email address for licensing purposes. You will receive your license agreement no more than 48 hours after purchase. Be sure to learn more and get your EquipmentTest download today!

The 19th Annual European APC Conference is in the books!

Posted by Alan Weber: Vice President, New Product Innovations on Apr 23, 2019 10:34:00 AM

apcm20191Cimetrix participated in the recent European Advanced Process Control and Manufacturing (apc|m) Conference, along with over 150 control professionals across the European and global semiconductor manufacturing industry. This site of this year’s conference was Villach, Austria, a picturesque town nestled in the eastern Alps just north of the Italian border in the state of Carinthia. This region is home to a number of high-tech companies and institutions all along the semiconductor manufacturing value chain, and since it was the first time the conference was held in Villach, the local hosts rolled out the red carpet. apcm20192-2

This conference, now in its 19th year and organized by Silicon Saxony, is one of only a few global events dedicated to the domain of semiconductor process control and directly supporting technologies. As usual, the conference was very well organized, and featured a wide range of high-quality presentations, keynote addresses, and tutorial sessions. The supplier exhibits associated with this year’s event were especially numerous, as were the technical posters displayed in the exhibition area just outside the conference rooms.

As in many prior years, Cimetrix was privileged to present at this conference, as Alan Weber delivered a talk entitled “Addressing Connectivity Challenges of Disparate Data Sources in Smart Manufacturing.” The presentation highlighted the need for unifying data collection concepts—like explicit equipment models and generic structures for data collection plans—are increasing necessary for maintaining the fidelity of a factory’s “digital twin” in Smart Manufacturing settings where the number of data source types is growing. This presentation resonated with a number of the key conference themes, so if you want to know more, feel free to download a copy of the entire presentation from our web site.

apc20193-1Other highlights of the conference included:

  • An update by Otto Graf on the ambitious vision and progress of the BOSCH 300mm wafer fab now under construction in Dresden. In this talk he emphasized the role that digital technologies will play in bringing up the fab and climbing the yield ramp and other features of a wall-to-wall Industrie 4.0 implementation. apcm20194-1
  • “The Role of APC and Smart Manufacturing / Industrie 4.0 in New Reliability-Critical Markets“ by James Moyne (University of Michigan / Applied Materials) – James re-presented a number of the Smart Manufacturing technologies in the context of automotive industry requirements, especially the role that Subject Matter Expertise (i.e., people!) will play alongside other emerging technologies. He also pointed out that the Factory Integration chapter of the International Roadmap for Devices and Systems (IRDS) will be reorganized around the key tenets of Smart Manufacturing.

  • A thought-provoking invited talk from Dr. Roman Kern of the KNOW-CENTER titled “Possibilities and Challenges of Digitalization in the Semiconductor and Other Domains.” His key messages started with “Big Data is the new oil…. AI is the new electricity… and Data Science is the new lingua franca for leading global industries,” and then he went deeper into all of these.

  • Dr. Germar Schneider of Infineon Technologies built on the theme above in a practical setting with his “Chances and Challenges of Digitization in Semiconductor Fabs and Success Factors during the implementation” presentation. This was not only an in-depth look at some of the multi-year efforts at Infineon, but also included a summary of current digitization projects across the European manufacturing R&D community. 

  • apcm20195-1Another invited talk from BMW was delivered by Rainer Hohenhoff which covered “Product Data and Product Life Cycle Management in the face of new business models of the automotive industry.” In short, it discussed many of the ways a car company might make money even after people stop buying as many cars as they do today… and what collisions (pun intended) you could expect in the market as service companies like Google, Amazon, UBER, and others converge on the transportation consumer. 

There were poignant moments as well. After 19 years of personal dedication to this event, both Gitta Haupold of Silicon Saxony and Dr. Klaus Kabitzsch, Program Committee Chair from Technical University of Dresden are retiring. They will definitely be missed!

apcm20196-1The insights gained from these and the other 30+ presentations are too numerous to list here, but in aggregate, they provided an excellent reminder of how relevant semiconductor technology has become for our comfort, sustenance, safety, and overall quality of life. 

This conference and its sister conference in the US are excellent venues to understand what manufacturers do with all the data they collect, so if this topic piques your interest, be sure to put these events on your calendar in the future. In the meantime, if you have questions about any of the above, or want to know how equipment connectivity and control fit into the overall Smart Manufacturing landscape, please contact us!

Multiple GEM Connections on Manufacturing Equipment

Posted by Brian Rubow: Director of Solutions Engineering on Apr 10, 2019 12:47:00 PM

The GEM standard is often incorrectly perceived as a single-connection protocol for manufacturing equipment. A single connection means that only one software product can use the GEM interface at one time. Many manufacturing equipment that support the GEM standard only have the ability for one connection. However, this limitation is set only in ignorance, by tradition, and to satisfy the common manufacturing system architecture. 

The truth is that the GEM standard simply does not discuss additional connections--meaning that additional connections are neither required nor prohibited. Not only is it possible for an equipment to support multiple concurrent GEM interfaces, this is becoming more and more common. If each supported GEM connection is point to point and complies with the GEM standard, this is certainly allowed. However, each connection should be completely independent of other GEM connections and still comply with the GEM requirements. Implementing multiple connections raises several questions. 

What does it mean for each GEM connection to be independent?

It means that each GEM host operates completely independently, as if the other GEM host connections were not present. Here is a more specific list of attributes that define “completely independent”:

  • The Communication state model is independent. Each can establish and disconnect independently from the other host packages.
  • The Control state model is independent. Each can be set up as local or remote as needed. 
  • Collection event report dynamic configuration is completely independent. Each host defines a unique set of reports and subscribes to a unique set of collection events. Even so, if two GEM host connections create identical reports and link them to the same collection event, then both should receive identical data. 
  • Each host subscribes to a unique set of alarms. 
  • Each host can query status information independently of any another.
  • Each host can choose to enable or disable Spooling and configure it as desired.
  • Each host can set up its own trace data collection.
  • Each host only receives messages based on its subscriptions.
  • Each host only sees reply messages to its primary messages.

Are you talking about HSMS-GS? 

No. HSMS-GS means implementing SEMI Standard E37.2, High Speed Message Service – General Session, an inactive SEMI standard. This standard, which never gained much industry traction, opens a single port through which any number of clients can connect. In contrast, I am talking about supporting multiple implementations of E37.1, High Speed Message Service – Single Session (HSMS-SS) where each connection uses a unique port number. Nearly all GEM interfaces today use the HSMS-SS protocol. 

What are the advantages of having multiple GEM connections in a single GEM interface? 

This opens the door for many useful applications. Here are three example configurations, and of course, all of them could be accomplished at the same time. 

  1. A factory can set up multiple host software packages at the same time to connect to the same equipment’s GEM interface, without any knowledge of or interference with each other. With only a single connection, a factory wanting to do the same thing has to implement some sort of GEM host broker to funnel the different GEM host package communications into a single GEM connection… a technically challenging feat. 01_GEMHost_v3
  2. If an equipment supplier wants to create an application designed specifically for its equipment running in a factory, they can use one of the GEM connections. They don’t have to replicate functionality into a custom interface. 02_GEMHost_v3
  3. If one equipment needs to monitor, control, or pass data directly to or from another equipment, this can be done using one of the GEM connections without interference to the factory GEM connection. This is relatively simple to set up. Sometimes this is called horizontal communication. Such communication can also be channeled through a host using the traditional vertical communication use case for a GEM interface. 03_GEMHost_v3

What about safety?

Typically, I would expect factories to set up one and only one connection in the GEM interface to be in the online-remote state and allowed to send remote commands. But this is not an absolute requirement. It is not difficult to imagine applications where execution of remote commands is distributed among multiple applications. For example, an equipment supplier might use one GEM connection to manage periodic recalibration of the equipment based the actual measured performance. 

What are the technical complications? 

There are a few. 

  • Because each connection uses a separate port number, the GEM interface can only support a finite number of connections when using HSMS-SS. 
  • Because multiple connections are not addressed explicitly in the standard, there are not requirements for handling them. For example, GEM requires that operator commands and operator recipe management activity be reported to the host. However, when another connection sends a remote command or downloads a new recipe, there is no requirement to report this. Our CIMConnect product does, but there are no formal requirements to do so. 
  • GEM requires the communication status to be displayed in the GUI, but what about multiple connections? It is not clear what needs to be displayed for multiple hosts. Typically I’ve just displayed the first GEM connection status, but it might be useful to show each connection status and give the operator a chance to control all GEM connections. 
  • Some collection events (and hence data variables), status variables and equipment constants are targeting the behavior of that single connection. This means that in order to implement multiple connections correctly, these connection-specific features must be unique for that connection. For example, consider status variables EventsEnabled and ControlState. The values reported for these two status variables are unique to that connection. This adds some complexity to implementing the GEM interface with multiple connections. Of course, our CIMConnect product implements and handles this already. 

Does each GEM connection have to be identical? 

No, but generally speaking it should be the same. The same set of collection events/data variables, alarms, status variables, and equipment constants should be reported to all connections. However, there are use cases where it might be useful to have some unique collection events and data on one connection. For example, if an equipment supplier uses one GEM connection as a pipeline for a factory host package dedicated to their equipment, they might want to publish some unique data that is for its eyes only. As mentioned above, if two GEM host connection create an identical report, and link it to the same collection event, then both should receive identical data. On the other hand, trace data reports with the same status variables may not need to report identical data, because the values might be sampled independently and at different time intervals. 

How many GEM connections should an equipment support in its GEM interface?

I recommend supporting five connections. Most GEM implementations are just using one connection today, so this opens the door for up to four more connections. This enables an equipment to handle most situations without the need to be reconfigured later at the factory. In CIMConnect, the overhead for having five connections is quite minimal, and virtually nothing if they are not used. 

What should the communication settings be? 

You should definitely set up the equipment as passive. This puts all of the configuration on the host side. The device ID can be the same for all connections, where 0, 1, or 32767 is best. 

How do I turn on multiple GEM connections in CIMConnect?

Since our CIMConnect product inherently supports multiple GEM connections, Cimetrix customers really only have to configure the setup file. Our CIMConnect GEM product was originally designed with multiple GEM connections in mind; therefore it is native and intuitive, with virtually no extra programming required unless you count the additional work in the operator interface. In the setup file, just create the five [CONNECTIONX] sections initially, and then set up a connection-specific VARIABLES and EVENTS section for each of the five connections. 

Alternative Approaches?

One alternative approach is to look at the SEMI Equipment Data Acquisition (EDA) standards. An EDA interface is inherently only for data collection and has multiple client access built into the standard as a fundamental requirement. The semiconductor front end device manufacturers have successful embraced this technology in addition to the GEM standard. The GEM interface is used by the Manufacturing Execution System for command and control of the equipment, while the EDA interface is used for every other application. 

Final Thoughts

My recommendation is that everyone, especially Cimetrix CIMConnect customers, take a look at their GEM interface and make sure that you are doing a good job implementing multiple host connections. CIMConnect makes this extremely easy. And let your customers know that you have this feature so that they can take advantage of it.

EDA Implementation Insights: What Data Should I Publish?

Posted by Derek Lindsey: Product Manager on Mar 19, 2019 11:30:00 AM

Previous blog posts have discussed the merits of choosing a commercial software platform for implementing the equipment side of EDA (Equipment Data Acquisition) and how you would use that package to differentiate your equipment data collection capabilities from your competitors.

In this post, we discuss how to design the equipment model to contain enough information to make it useful without publishing so much data that it becomes cumbersome for your factory customers to find the data that is most important to them.

Data to Publish

The automation requirements for the most advanced fabs call for the latest versions (Freeze II) of all the standards in the EDA suite, including the EDA Common Metadata (SEMI E164) standard. In addition to providing an excellent foundation for a new equipment model, E164 enables consistent implementation of GEM300, commonality across equipment types, automation of many data collection processes, less work to interpret collected data, and true plug-and-play client applications—all of which contribute to major increases in engineering efficiency. These capabilities benefit both the equipment suppliers and their factory customers alike. Therefore, equipment models should make all E164-compliant data available.

To summarize, those who remember the complexity of implementing SECS-II before GEM came along (pre-1992) will understand this analogy: E164 is to EDA what GEM was to SECS-II.

  • Fab-specified Data

The second blog post made the following statement:

“In effect, the metadata model IS the data collection 'contract' between the equipment supplier and the fab customer."

“This is why the most advanced fabs have been far more explicit in their automation purchase specifications with respect to equipment model content, going so far as to specify the level of detailed information they want to collect about process performance, equipment behavior, internal control parameters, setpoints and real-time response of common mechanisms.”

You only have to read the latest requirements specs for these fabs to get more specifics. Pick the one from your customer base that sets the bar highest and let that be your target.

Data to Avoid in the Model

It is easy to fall into the mindset that if publishing some data through the EDA interface is desirable, the more data we can publish, the better. This is not always the case. In his fascinating book, The Paradox of Choice, Barry Schwartz makes the case that freedom is defined by one’s ability to choose, but more choice doesn’t mean more freedom. In fact, too many choices actually cripple one’s ability to choose. The same can be said of data published in an EDA interface. Making too much data available actually hinders the creation of EDA client applications.information-overload-1-1

We were recently working with a fab to perform a proof-of-concept where we connected an EDA client to a piece of equipment with an EDA interface. We were able to connect to the equipment in a matter of minutes, but finding suitable data to collect for our proof-of-concept took almost an hour because there was so much superfluous data published from the equipment.

Publishing everything including the kitchen sink reduces the ability to create an efficient EDA client application.

Some examples of data to avoid publishing in the model include:

  • Parameters that have no value – If a parameter is available in the model, but the value is not published by the equipment control application, that parameter is just extra noise in the interface. Consider not adding it to the model.
  • Parameters with values that do not change – If a parameter value does not change during the life of the application, it does not make sense to collect that parameter’s data. For example, if an application uses an equipment constant, it may not be necessary to publish that constant through the EDA model.
  • Irrelevant data – If a parameter contains data that is irrelevant to data publication, it should not be added to the model. For example, having parameters in the model that contain the IP address or port number for connection are not very useful in the equipment model. This information is necessary in connecting with an EDA client, but is not relevant for data collection in the model.

The takeaway: Publish data required by E164 and additional fab-specified data, but carefully evaluate other data to be published to make sure it is relevant and useful for data collection.
