Abstract: Exemplary methods, apparatuses, and products are described for creating a behavioral model of a hardware device for use in a simulation environment. The behavioral model is created by an iterative process that includes receiving in a simulated hardware device from a simulated device under test (‘DUT’) a stimulus waveform. The stimulus waveform includes data representing a number of stimuli. In response to receiving the stimulus waveform, the simulated hardware device presents a recorded response waveform from a recorded response file to the DUT. The stimulus waveform is also recorded. The recorded stimulus waveform is presented to the hardware device. A response waveform that results from presenting the recorded stimulus waveform to the hardware device is recorded in the recorded response file.

Abstract: Methods, apparatus, and computer program products are described for verifying a simulated hardware environment for a simulated device under test (‘DUT’) that include recording, in a software domain, interface signals between the simulated DUT and a simulated hardware device of the simulated hardware environment, the interface signals also including simulated stimulus interface signals and simulated response interface signals; exporting, from the software domain to a playback device of a hardware domain, the recorded interface signals, including the simulated stimulus interface signals and the simulated response interface signals; and playing the exported, recorded simulated stimulus interface signals in the hardware domain from the playback device to the hardware device. In typical embodiments, the hardware device in the hardware domain also including an actual hardware part operating under actual conditions of voltage, frequency, and temperature.
