Portable Stimulus and VIP: Like a Hand in a Glove
One of my favorite things about DAC is the ability to share with so many of you some details of the exciting new technologies we’re developing here at Siemens. This year we added a video recording studio to our booth so that we could create high-quality videos of the presentations that we shared in the booth. Many of you know that I am particularly passionate about the Portable Stimulus Standard (PSS) and wanted to let you know that my recording of “Portable Stimulus and Verification IP Fit Together Like a Hand in a Glove” is now available on Verification Academy.
In this video, I talk about how the Portable Stimulus Standard (PSS) encourages verification engineers to focus on describing test scenarios, without worrying about the underlying target environment on which the test will ultimately be run. By describing the scenarios in terms of a randomizable schedule of actions, or behaviors that will execute, the test can easily be retargeted to different implementations for different environments.
The image at the top of this post is a partial screenshot from the video. The white bubbles in the activity graph are specific actions required to model the verification intent. The orange bubbles are additional actions that our Questa Portable Stimulus tool inferred from the model to make the explicit scenario legal. In the video, I show how several different complex scenarios can be generated from the same relatively simple model. The waveform below the graph shows how we add transaction recording to the flow so you can see the execution of your PSS model in simulation.
We’ve also gathered all of our DAC 2024 videos here for your perusal.
