Formal-Based Techniques
Formal-Based Techniques
This topic area focuses on formal-based techniques, ranging from formal property checking to clock-domain crossing (CDC) verification. Assertion-based verification (as it relates to formal property checking) is also covered in this topic area.

Synthesizing Assertions into Hardware for Faster Silicon Debug
Assertions are already used in pre-silicon verification and can help halve debug time. So why not synthesize assertions into real logic gates in the final silicon, to catch those unexpected bugs that make validation so much harder? Here’s how.

A Unified Verification Flow Using Assertion Synthesis Technology
As SOC integration complexity grows tremendously in the last decade, traditional blackbox checker based verification methodology fails to keep up to provide enough observability needed. Assertion-based verification (ABV) methodology is widely recognized as a solution to this problem.
