EDA Tech Forum Journal—the premier EDA publication

EDA Tech Forum journal is a quarterly publication for the Electronics Design Automation community including design engineers, engineering managers, industry executives, and academia. EDA Tech Forum journal provides an ongoing medium in which to discuss, debate, and communicate the electronic design automation industry’s most pressing issues, challenges, methodologies, problem-solving techniques, and trends.

Multiple cross clock domain verification

Today’s system-on-chip designs often need to encompass multiple asynchronous clocks. This raises the problem of verification for the resultant clock domain crossings.

It is becoming apparent that functional simulation alone is not up to the task. Instead, engineers need to consider hybrid methodologies, combining structural and functional verification approaches.

The use of assertions is also proving increasingly important to CDC verification, and the author provides examples of code he built to address the techniques and features demanded by increasingly complex designs.
