A Robust Framework for High Speed Link Verification with a Proficient Way to Close the Functional Coverage
DescriptionThe motive of the proposed work is to discuss a general verification framework which reduces the effort and time taken in High-Speed Link DV activity while maintaining the quality. Simulation time can be reduced to a great extent by introducing save-and-restore mechanism which cuts down the repeated simulation activity like link initialization and training. In complex Link design like UniPro, there are many functional coverage bins and it is very hard to cover that many bins with random regression given the time constraint. A smart coverage closure technique is discussed involving test ranking and Perl script integration for quick turnaround. The script extracts the statistics of un-hit bins and creates a directed test suite to hit those specific bins with a single run. Also, to find bug at the initial stage of verification some scenarios are proposed which create simulation condition close to the real world by incorporating skew and lane mapping.
