CAUSALITY ENFORCEMENT FOR ELECTRICAL INTERCONNECTS THROUGH PERIODIC CONTINUATIONS

摘要

Causality evaluation for transfer functions representing the behavior of electrical interconnects of a system is provided herein. An initial transfer function can be received that represents the behavior of electrical interconnects of a system over an initial frequency range. A causal, periodic continuation can then be constructed based on the initial transfer function and one or more causality conditions. The continuation is periodic over an extended frequency range that is larger than the initial frequency range. At a plurality of frequencies, values for the initial transfer function and values for the continuation can be compared. The causality of the initial transfer function can be assessed based on the comparing.

receiving an initial transfer function representing the behavior of electrical interconnects of a system over an initial frequency range; constructing a causal, periodic continuation based on the initial transfer function and one or more causality conditions, the continuation being periodic over an extended frequency range that is larger than the initial frequency range; comparing, at a plurality of frequencies, values for the initial transfer function and values for the continuation; and assessing causality of the initial transfer function based on the comparing.
