CIRCUIT SYNTHESIS METHOD USING TECHNOLOGY PARAMETERS EXTRACTING CIRCUIT

摘要

A method of synthesizing a circuit employs a technology (18) parameter extraction circuit which is synthesized with constraints (12) and simulated to derive values of performance parameters, and then, based on the derived values, a predetermined high-level circuit description of a circuit is modified and then synthesized using the same constraints. Optional steps include the creation and substitution of a sub-circuit (142) model to permit correct simulation, or substitution of an alternative sub-circuit to synthesize a second circuit (22) that cannot otherwise be synthesized directly.
