PCI Express verification underscores need to planLevent Caglar, Cadence Design Systems Inc. (11/07/2005 10:00 AM EST) EE Times PCI Express-based designs are textbook examples of a complex verification problem. Using a compliance checklist can kick-start verification planning. But you also need a well-planned verification methodology that addresses these questions: What compliance items are verified? Have you covered all compliance scenarios? Can you provide a progress report to your manager? These challenges are not new for verification engineers. But complex verification projects force the extended team to do more planning, to avoid getting lost in the 1,300+ item compliance checklist. An extensive checklist can serve as a compliance verification plan to identify how to co-relate compliance items to the data automatically provided by the verification environment. This involves mapping English definitions to a mechanism. Often, we underestimate the workload and get confused between checking a single scenario and proving that a specific feature works in all scenarios.
