Patent ID: 7379856

Claim:
A method comprising: (a) receiving a measured electrical signal response in at least one of time domain or frequency domain, wherein the measured electrical signal response represents an electrical behavior of an electronic device; (b) sampling the received measured electrical signal response at a plurality of sampling points and approximating each section of the received measured electrical signal response between two adjacent sampling points by a respective linear curve section; (c) for each section of the received measured electrical signal response between two adjacent sampling points: (i) selecting a pulse unit for generating a pulse having a transition between the two adjacent sampling points associated with the section; and (ii) selecting a current source or a voltage source providing, in response to the pulse from the selected pulse unit, an output signal corresponding to a slope of the section; (d) selecting an integrating unit for superimposing the output signals from each of the selected current or voltage sources for generating an approximated signal response; and (e) creating a model of the electronic device based on the selected pulse units, the selected current or voltage sources and the selected integrating unit.
