Abstract

See full text

A simulation method, simulation device and a readable storage medium are disclosed, in which a correction circuit is added to an equivalent circuit model for a three-terminal circuit employed in a SPICE simulation system. The correction circuit enables simulating behavior of the resistor module, enabling the SPICE simulation system to take in account the body effect. Therefore, simulation results obtained from the simulation model and simulation parameters for the resistor module can better reflect resistor behavior with body effect in an actual circuit, resulting in effectively improved simulation accuracy of the SPICE simulation system and allowing the system to provide more accurate circuit simulation results. Fitting tests can be performed to obtain first-order, second-order and resistor-width-dependent correction coefficients for a body voltage of the resistor module. Thus dependence of resistor behavior on the body voltage can be better predicted, allowing a good reflection of resistor behavior with body effect.
