1. A computer-implemented method for validating different design representations, the method comprising: loading a reference representation of a design; loading a compared representation of the design, wherein: the reference and compared representations are intended to respond to stimulus in the same way, and the reference representation is at a different level of abstraction than the compared representation; simulating, using one or more processors, the reference representation to generate first waveform signals and first measured results; simulating, using the one or more processors, the compared representation to generate second waveform signals and second measured results; comparing, using the one or more processors, the first waveform signals and second waveform signals to identify waveform signal violations; and comparing, using the one or more processors, the first measured results and the second measured results to identify measured result violations.
