Abstract
The present invention is directed to a simulation testbench which includes a circuit under test and a plurality of test models designated through N. The test models include at least one of a driver and a monitor. The drivers selectively apply stimuli to the circuit under test and the monitors observe responses to the stimuli from the circuit under test A single controller is provided for the plurality of test models The controller has an instruction source including a list of commands which control the plurality of test models The commands are routed from the instruction source over a model control bus to the plurality of test models In a preferred embodiment, a common bus interface links each test model to the model control bus and a sequencer addresses the instruction source to put successive commands out on the model control bus where they are accessed via the common bus interfaces associated with the test models for which the commands are intended.
