Abstract
A method for implementing physical optimizations includes performing physical optimizations on a first reference version of a design, maintaining a computer-readable list of the physical optimizations, and during a subsequent compile for a second version of the design: identifying matching cells, nets, or both between the first reference version of the design and the second version of the design; and restoring at least a subset of the physical optimizations in the second version of the design by reading the computer-readable list of the physical optimizations and applying the subset to a computer-readable description of the second version of the design.
