Abstract:
A system and a method for correcting early-mode timing violations that operate across the process space of a circuit design. Optimizations are performed to replace padding that increase path delays on fast paths. At the stage in the design process where early-mode violations are addressed, placement, late-mode timing closure, routing, and detailed electrical and timing analysis are assumed to have been completed. The optimizations are designed to be effective in delaying fast paths while minimizing the impact on already-completed work on the chip, in contrast to relying only on adding pads that can have a negative impact on all of these quantities. The optimizations are classified according to their invasiveness and are followed by their deployment. The deployment is designed to minimize using delay pads, reduce design disruptions, and minimize effects on other aspects of the design.
