Implementation of alternate solutions in technology mapping and placement

摘要

A computer-implemented method of implementing a circuit design within a target integrated circuit (IC) can include, during technology mapping of the circuit design, determining a plurality of implementations of at least one sub-circuit of the circuit design and placing the circuit design on the target IC using a primary implementation of the plurality of implementations of the sub-circuit. The primary implementation of the sub-circuit can be selectively replaced with an alternate implementation of the sub-circuit selected from the plurality of implementations of the sub-circuit. The placed circuit design, including either the primary implementation or the alternate implementation of the sub-circuit, can be output.
