In this track we address managing diversity, amongst others by testing only those features impacted by a change, and only test on a specific and limited selection of configurations, thus creating confidence that your change will work on all configurations.

Testing Product Lines based on Evolving Requirements

As systems evolve to keep pace with changing business and market needs, they usually become more complex and diverse. As a result, it is increasingly costly and time consuming to release new versions of the system following an update or an upgrade, while providing guarantees on their quality.

This talk presents a methodology to improve efficiency and effectiveness of current testing processes in industry. Using an intuitive template-based approach to specify system requirements as constraints in natural language, we enable behavior-based traceability towards test specifications. As a consequence, it is possible to get instant insights into conformance and coverage, generate only the missing test scenarios per system configuration, as well as compute a selection of relevant tests and system configurations to cover for changes to system specifications. To further improve the precision of test selection techniques, a vision is presented to incorporate additional sources of information such as changes to source code and usage profiles from the field.

From Nuts to Nodes along the game trail

Integrating and verifying the complexity and diversity of lithographic manufacturing

 These days, the world runs on semiconductor chips. Usage is as diverse as big datacenter, automobiles, kitchen and lighting appliances,  smart-phones and personal health monitoring. All of these different applications require the different types of semiconductor chips.

The most advanced semiconductor chips can contain up to 200 layers, with a single layer requiring up to 60 manufacturing process steps. ASML products play an essential role in the manufacturing of these chips. One of our products, the EUV scanner,  has been called “Likely the most complicated machine humans have ever built”.

The complexity and diversity of the lithography processes make chip manufacturing costly. Therefore, it is essential to verify upfront that all products and processes will work seamlessly together in the volume manufacturing environment of the customers. This starts at the lowest level of components (the nuts) and extends to the exact configurations of products and use-cases the customers runs in the fab. Verifying this node solution requires to integrate systems early, potentially virtual, fast and above all asks for extended collaboration between individual development teams and with the customer.
