Abstract:
A method for use in simulation of single and coupled lossy lines, comprising the steps of:employing a database storing a number of triangle inpulse responses as V-t or I-t curves of lossy transmission lines created use of a test circuit schematic input to a simulation tool for generating triangle inpulse responses for said test circuit; and generating with said simulation tool the stored number of said triangle inpulse responses and storing the stored number of triangle inpulse responses in said database as V-t or I-t curves for retrieval by a database request; and during a simulation for an integrated circuit (IC) package for determining how the IC package is to be laid out on a chip providing as a input to a simulation tool a netlist for said IC package, and thereafter calculating with a circuit simulation tool iteratively with the use of triangle waveforms represented as time domain basis functions for the netlist for said IC package and requests for triangle impulse responses from said database of lossy transmission lines the time domain response of transmission lines of said IC package for said netlist in order to verify the existing design for said IC package.
