摘要： A system and method of adjusting the logic synthesis process of the design of an integrated circuit takes into account the interaction between the IC core logic circuitry, the on-chip power supply circuitry, and the package power supply circuitry. In IC package/circuit technology combinations that have been employed in previous IC designs, the associated package and on-chip power supply circuit designs are stable and well-defined, thus allowing the generating of simulation models for those power supply circuits. Those models are used to identify resonant frequencies and other characteristics of the power supply circuitry. By using the identity of the power supply resonant frequencies and the power supply models themselves, design constraints are developed that are supplied as input, either directly or indirectly, to the logic synthesis process to avoid incompatibilities of a periodic and non-periodic nature between the IC core logic and the power supply circuitry.
