Patent ID: 7546230

Claim:
A computer-readable medium having stored thereon a plurality of instructions for circuit design modeling electromagnetic responses in a particular circuit interconnect medium, the plurality of instructions including instructions that, when executed by a processor, cause the processor to: a) model said medium as a Partial Element Equivalent Circuit (PEEC) model of a network of passive elements having an active operating frequency range (f active ) and coupled power supplies, said coupled supplies being delayed (τ) capacitive-current-controlled current sources having the form I Ck = p km p mm ⁢ i c ⁡ ( t - τ ) , and delayed inductance-voltage-controlled voltage sources having the form v L = Lp ⁢ ⅆ i ⁡ ( t - τ ) ⅆ t , and providing power responsive to conduction in at least one corresponding coupled passive element, where i c is branch current and p km /p mm and Lp are capacitive and inductive coupling factors, respectively; and b) low pass filter each of said coupled supplies comprising inserting a low pass filter between each of said capacitive-current-controlled current sources and said passive elements in said PEEC model, wherein said coupled supplies are low pass filtered to block frequencies at least 2 times f active , the processor selectively storing the low pass filter results in a computer-readable medium.
