Method and apparatus for performing fast incremental physical design optimization

摘要

A method for designing a system on a target device includes generating a first netlist for a first version of the system after performing synthesis in a first compilation. Optimizations are performed on the first version of the system during placement and routing in the first compilation resulting in a second netlist. A third netlist is generated for a second version of the system after performing synthesis in a second compilation. A hybrid netlist is generated from the first, second, and third netlists. Incremental placement and routing are performed on portions of the hybrid netlist that are new to the first compilation.

1. A method for designing a system on a target device, comprising:
generating a first netlist for a first version of the system after performing synthesis in a first compilation; performing optimizations on the first version of the system during placement and routing in the first compilation resulting in a second netlist; generating a third netlist for a second version of the system after performing synthesis in a second compilation; generating a hybrid netlist from the first, second, and third netlists; and performing incremental placement and routing on portions of the hybrid netlist that are new to the first compilation.
