Pre-Mortem Waveform Trace Generation for Hardware Description Language Simulators

摘要

A computer implemented method, system and computer program product for providing a waveform trace of a last plurality of cycles of a simulation prior to occurrence of an error in the simulation. A computer implemented method in a data processing system for providing a waveform trace for a last plurality of cycles of a simulation prior to occurrence of an error in the simulation includes storing history information relating to a last plurality of cycles of a simulation during running of the simulation. Responsive to an error occurring in the simulation, the simulation is stopped, and a waveform trace for the last plurality of cycles of the simulation is provided using the stored history information.
