Abstract
A placement tool that may import and export cell substitution and/or cell selection lists. The cell substitution and/or cell selection lists may be used by the placement tool to substitute and/or modify the placement design database, rather than the original schematic or behavioral database. This may eliminate the need to re-synthesize the circuit design during each design iteration. The present invention further contemplates providing a reset feature which may reset the circuit design database to a previous state, if desired.
