  • Patent number: 8515725
    Abstract: A system, method and computer program product for modeling a semiconductor device structure. The system and method implemented includes performing a simulation of the circuit by applying at least one input waveform on a circuit input port, and loading an output port with at least one of output load; determining, at successive time steps of the circuit simulation, a voltage value Vi on the input port, a voltage value Vo on the output port, and a current values (ia) and (ib) on the respective input and output ports. Then there is computed from the respective current value for each successive time step of the simulation, at least one charge value (Qa(Vi, Vo)) and (Qb(Vi, Vo)), respectively, as a function of Vi and Vo voltage values; and generating a nonlinear charge source from the at least one charge value, the nonlinear charge source used in modeling a dynamic behavior of the cell. A voltage controlled charge source (VCCS) is thereby determined by capturing the natural digital circuit cell behavior.
