Exploring Essential Concepts in Formal Verification
Resource (Verification Horizons Blog) - Sep 18, 2024 by Nicolae Tusinschi
A witness is a sequence of inputs that demonstrates how an assertion is satisfied, showing that the design behaves as expected. A counterexample, on the other hand, is a sequence of inputs that violates an assertion, indicating a potential bug or design flaw. Both can be used to generate simulation tests that help engineers debug and verify the design.

Accelerate Closure of Reset Path and Reset Domain Crossing Issues in Digital Designs
Resource (Verification Horizons Blog) - Jul 24, 2024 by Farhad Ahmed
In tight project windows, engineers tend to use waiver mechanisms and/or use constraints (i.e., setting false paths) to completely eliminate paths from reset domain crossing (RDC) analysis, which can result in RDC bug escapes. In a recent DVCon conference presentation, a design engineer declared “jihad” against such use of waivers and constraints to remove certain reset paths from being properly analyzed.
