Debugging is like a detective work. It’s an iterative process to eliminate the suspects using the clues to reach the cause. The detective work requires…
Full Regressions in Verification
Full regressions are ideally are required for every change. But it’s not practically possible in many real life use cases. Role of regression is to keep all…
Check-in regressions in Verification
Regressions are process to keep the passing tests in passing state. Ideally in order to do that full regressions should be run for every change.Since…
Role of Regressions in Verification
Imagine a floor of the engineers working on design and verification of an interesting DUT. Designers are improving DUT’s strength everyday by adding new features. Verification…

Verification methodology
Verification methodology provides a framework for easing implementation of coverage driven constrained random verification environments. Verification methodology by itself will not do any functional verification. It’s just an enabler….
High-level verification language (HVL)
High-level verification languages can also be termed as domain specific languages. Domain specific languages pack more power than the generic programming languages for those domain…
Tests
Tests are are the top most layer of verification environment. Tests create the scenarios to verify if the DUT meets the requirement specification. Tests utilize…
