Abstract:
1. A computer-implemented method for creating a behavioral model of a hardware device for use in a simulation environment, the method comprising iteratively carrying out the steps of: receiving in a simulated hardware device from a simulated device under test (‘DUT’) a stimulus waveform, the stimulus waveform comprising data representing a number of stimuli; recording the stimulus waveform, including recording delay data representing delays between presentation of a response and receipt of a next stimulus; responsive to receiving the stimulus waveform, presenting, by the simulated hardware device to the simulated DUT, a recorded response waveform from a recorded response file; presenting the recorded stimulus waveform to the hardware device; recording in the recorded response file a response waveform that results from presenting the recorded stimulus waveform to the hardware device, including recording delay data representing a delay between receipt of a stimulus and presentation of a corresponding response; and synchronizing the recorded response waveform to the stimulus waveform while presenting recorded response waveform to the simulated DUT.
