Abstract:
A bidirectional communications stimulus interface for a logic simulator, said logic simulator being responsive to input stimuli for performing a logic simulation of a simulated circuit representing a simulator model of a circuit design and which gives logic values of respective nodes of the simulated circuit, said interface comprising:adaptive means for processing procedural vectors, which model an environment external to the simulated circuit, in realtime using current simulated logic values of the respective nodes of the simulated circuit to determine next input stimuli for the logic simulator for setting logic values of the respective nodes of the simulated circuit; and bidirectional communication means operating between the logic simulator and the adaptive means for providing the next input stimuli determined by the adaptive means to the logic simulator and for providing the current simulated logic values of the respective nodes of the simulated circuit from the logic simulator to the adaptive means for use thereby in determining the next input stimuli.
