Optimized mapping of an integrated circuit design to multiple cell libraries during a single synthesis pass

摘要

A circuit design synthesis method is provided comprising: associating a first cell library with a first block of a circuit design; associating a second cell library with a second block of the circuit design; specifying at least one constraint upon the overall circuit design; mapping a portion of the first block to a cell in the first cell library based upon the at least one constraint in view of a step of mapping a portion of the second block to a cell in the second cell library; and mapping a portion of the second block to a cell in the second cell library based upon the at least one constraint in view of the step of mapping a portion of the first block to a cell in the first cell library.
