System and method for guiding remedial transformations of a circuit design defined by physical implementation data to reduce needed physical corrections for detected timing violations in the circuit design
System and method for guiding remedial transformations of a circuit design defined by physical implementation data to reduce needed physical corrections for detected timing violations in the circuit design
A system and method are provided for pessimism reduction of a timing database provided for optimization of a circuit design. Pessimism is reduced through generation of a hybrid graph-based static timing analysis (GBA) and path-based static timing analysis (PBA STA) database. PBA is selectively performed on the most critical GBA identified timing violations with the goal of reducing erroneous pessimism in operational timing characteristics passed on to the physical implementation corrective optimizer module to thereby reduce unnecessary fixing and transformations upon the circuit design to correspondingly reduce design time, temporary storage space, needed processing power for timing closure and to result in a finished operable and tangible circuit device with reduced area, power requirements, and decreased cost.
