Claim One:
1. A method for modeling a receiver load, comprising: using a computer, representing the receiver load with a static capacitance in parallel with a current source in a simulated circuit comprising a driver and a receiver, wherein the receiver load includes anomalies caused by at least one physical phenomenon; characterizing the static capacitance and the current source from a timing library by: (i) estimating a receiver input waveform slew rate and extracting a corresponding static capacitance value from the timing library; (ii) simulating a nonlinear circuit voltage response by including the static capacitance value in the circuit; (iii) computing a linearized dynamic current correction represented by the current source, wherein the linearized dynamic current is caused by the at least one physical phenomenon; and (iv) determining a voltage correction due to the current source and adding the voltage correction to the simulated nonlinear circuit voltage response; iterating (i) to (iv) until specified simulation convergence criteria are satisfied; upon determining that the specified simulation convergence criteria are satisfied, outputting the simulation results comprising the nonlinear circuit voltage response; and fabricating the receiver load based on the simulation results.
