Patent ID: 7281223

Claim:
A method for modeling an integrated circuit system including a microchip, an integrated circuit package, and a printed circuit board, the method comprising: generating a configuration file including parasitics regarding ball grid arrays and vias intended for use in design of the integrated circuit system; generating, using the configuration file, a netlist including a top level netlist, which further comprises: a printed circuit board netlist; an hierarchical package netlist that abstracts physical behavior of the parasitics and is configured using mathematical models of ideal capacitors for power planes and ground planes of the integrated circuit package, representing the vias and the BGAs as distributed, multistage networks and wherein lumped numbers for inductance, resistance and capacitance are distributed to a reselected number of stages; and an hierarchical chip level netlist that abstracts behavior of the chip; and simulating, based upon the configuration file, operation of the integrated circuit system to determine anticipated operating characteristics of the integrated circuit system.
