Abstract
A method and a corresponding apparatus provides for modeling circuit environmental sensitivity for a basic minimal level sensitive timing abstraction model. Environmental issues typically include different external conditions, such as input signal switching time and output capacitive loading for the circuit, that are influenced by the circuitry surrounding the basic timing abstraction model. The method for modeling circuit environmental sensitivity involves creation of delay components that allow for modeling the circuit environmental sensitivities while maintaining the transparent regions of the circuit. To properly model the environment effects, zero delay elements may be inserted at input and output ports of the basic timing abstraction model, producing an improved abstraction model that retains accuracy and efficiency of the basic timing abstraction model.
