Verification using various methodologies has become popular as it saves VE development time. Even more time can be saved if we think of possible reuse of various VE components when defining the VE architecture. The reuse of VE components at different levels is crucial to time-saving during design verification, with applications comprising block, cluster/subsystem, chip, or SoC levels, and can also result in huge time savings during post-silicon lab validation.

This paper talks about an API- (Application Program Interface) based verification approach that can be adopted for a whole segment of ASIC applications.

Let’s focus on design blocks B1, B2, and B3 of the example SoC in Figure 1. These blocks are interconnected using unique interfaces and each one of them is to be verified independently at the block level followed by cluster and chip levels.
