What is ABV ?
Modern SoC and ASIC design flow based on EDA tools have greatly enabled the handling of design complexity with the growing demands of various applications. One of the greatest challenges for the design teams is ensuring the functional correctness of the RTL design. Extensive verification is carried out to ensure that bugs are discovered early in the design flow as a bug discovered in post SoC fabrication testing would require costly silicon re-spin. However, there is an embedded goal in this challenge to shorten the verification cycle. New techniques are being researched to tackle the problem of test complexity by evolving the existing verification methodologies. Formal verification, an advancement over the conventional simulation based verification has been there for quite some time. The concept of property checking led to Assertion based verification which is a methodology used in functional property verification. It is aimed to improve the controllability and observability of deeply
