ABSTRACT:
The present invention provides a method and a computer-readable program for providing generation of graphical congestion images during placement driven synthesis optimization. These graphical congestion images enable a design engineer to make changes and/or improvements to subsequent processes in the design flow before the current placement driven synthesis step completes, thus saving time. This information also provides valuable debug information to PDS developers.
