Efficient Reset Metastability SignOff Methodology
DescriptionReset metastability signoff has become imperative as modern designs increasingly rely
on software resets. This introduces risks where parts of the design remain under reset
while others operate functionally, and improper handling of resets across power
domains can potentially lead to chip failures. Reset controllers are designed to ensure
no reset metastability issues occur, but they may miss metastability arising from
asynchronous crossings or inadequate synchronization of reset signals.
Traditional methodologies like STA, functional verification, and CDC do not catch all
reset metastability issues to ensure signoff. Primitive static solutions face capacity
limitations, prohibitively high noise, and convoluted flows. Linking static signoff to
simulation or formal methods results in slower turnaround times and missed issues.
This presentation introduces a novel Reset Domain Crossing (RDC) methodology that
overcomes these challenges. The approach is scalable to designs of any size and
significantly reduces time and effort, ensuring robust reset metastability signoff. It delivers
faster turnaround times, improved coverage, and a streamlined flow compared to traditional
methods
