Once a behavioral •Behavioral simulation or functional simulation predicts that a system works correctly, the next step is to check the •Functional simulation timing performance. •Static timing analysis timing simulation: At this point a system is partitioned into ASICs, •Gate-level simulation timing simulation is performed for each ASIC separately. static timing analysis : does not require the creation of a set of •Switch-level simulation test (or s
