As regular readers know, Breker’s claim to fame is the automatic generation of multi-threaded, self-verifying test cases that run on multiple heterogeneous processors within an SoC. The source for the generation process is a graph-based scenario model that captures the design intent and verification space. We chose graphs as an enabling technology more than ten years ago for a number of reasons, some of which we’ll discuss in this post.
The catalyst for this discussion is a new effort within the Accellera standards body to form the Portable Stimulus Specification Proposed Working Group (PWG). Basically, Accellera has formed a proposed working group to determine whether a technical working group should be established to start developing a specification for a standard. What does this have to do with graphs, and Breker? We’ll do our best to explain the history and current status.
