How does timing verification work?
Every device path in design must be analyzed with respect to timing specifications/requirements
Catch timing-related errors faster and easier than gate-level simulation & board testing
Designer must enter timing requirements & exceptions
Used to guide fitter during placement & routing Used to compare against actual results
