Why Portable Stimulus Must Be Bidirectional

Thursday, August 18th, 2016

When we first began offering our Trek family of products for what’s now known as portable stimulus, we talked a lot about vertical and horizontal reuse. Vertical reuse means that you can create a scenario model for individual IP blocks and generate test cases to run in their UVM testbenches, then move up to clusters and subsystems. The IP models can simply be plugged together to form a higher-level model from which appropriate higher-level test cases can be generated.

At the full-SoC level, you can generate C test cases that run on your embedded processors. Horizontal reuse is the ability to move from simulation to hardware (acceleration/emulation, FPGA prototypes, and silicon) while generating appropriate tests for these platforms from the same SoC scenario model. We generally described both forms of reuse in a unidirectional flow. However, bidirectionality is very valuable and, we believe, essential for portable stimulus. Let’s cover that topic in today’s blog post.
