Systems and methods for streaming waveform data during emulation run

Abstract:

An exemplary emulation computer may allocate a portion of its emulation memory for capturing probe data during a runtime of emulating a device under test (DUT). The emulation computer may instantiate a plurality of streaming probes from dynamic netlists provided by a user. The streaming probes may capture non-transitory internal signals within the DUT and transmit the captured non-transitory internal signals to the allocated portion of the emulation memory, which in turn may store the received signals as waveform data records. During the runtime of emulating the DUT, the emulation computer may receive an upload request for the waveform data records from a workstation computer. In response to the request, the emulation computer may transmit the waveform data records to the workstation computer. The emulation computer does not have to pause or stop the runtime of emulating the DUT while transmitting the data records to the workstation computer.
