Abstract
A system for dynamically representing repetitive loads of a circuit during simulation includes a simulator module having one or more computer programs for 1) identifying one or more driver circuits for driving a plurality of repetitive receiver circuits, where each driver circuit has an output port and each repetitive receiver circuit has an input port, 2) creating a branch node driver for connecting the input ports of the plurality of repetitive receiver circuits and the output ports of the one or more driver circuits, 3) creating a shared load for representing aggregated input port loads of the plurality of receiver circuits having a substantially same isomorphic behavior, 4) creating a port connectivity interface for communicating changes of signal conditions between the output ports of the one or more driver circuits and the corresponding input ports of the plurality of repetitive receiver circuits, and 5) simulating the one or more driver circuits and the plurality of repetitive receiver circuits in accordance with the branch node driver, the shared load and the port connectivity interface.
