Method for Computing a Circuit Simulation with Respect to a Driver

A method for computing a first circuit simulation with respect to a driver comprising:

• (a) inserting a recorded pair of slope related delays associated with the driver into one selected set of data points;
• fitting a respective delay related to a layout of a wiring tree and parameters related to a set of switches that adds capacitive loading to the set of stages, wherein a maximum of an absolute value of one or more computed prediction errors is minimized;
• computing corresponding values for the delay related to the layout of the wiring tree and the parameters related to the set of switches that adds capacitive loading to the set of stages;
• recording the computed corresponding values for the delay related to a layout of the wiring tree and the parameters related to the set of switches that adds capacitive loading to the set of stages, in which the recorded pair of the slope related delays associated with the driver, and the recording values for the delay related to the layout of the wiring tree and the parameters related to the set of switches that adds capacitive loading to the set of stages are written to a computer readable storage medium;
• and
• recording a pair of slope related delays associated with the driver, in which the set of stages includes at least one fanout, each of at least one fanout spanning from the driver of the set of stages to one or more receivers thereof, and coupled to the driver with the wiring tree thereof between the driver and the receiver, and an active path in the at least one fanout from the driver to the receiver includes at least one switch in a conductive ‘on’ state.
