VISUALIZATION CONSTRAINTS FOR CIRCUIT DESIGNS

摘要

A first waveform for a circuit design is received. The first waveform includes at least an actual value of a signal of the circuit design at one or more clock cycles. A user input for a cursor is received, and a signal wave overlay is displayed on the first waveform having an appearance corresponding to a location of the cursor. The signal wave overlay indicates a desired value of the signal at one or more clock cycles that is different than the actual value of the signal in the one or more clock cycles. Based on the desired value of the signal indicated by the signal wave overlay, a visualization constraint for the circuit design is generated. The visualization constraint is used to generate a second waveform, where the visualization constraint restricts the second waveform.

1. A computer program product for interactively generating constraints for a circuit design, the computer program product comprising a non-transitory computer-readable storage medium comprising computer program code for:
receiving a first waveform for the circuit design, the first waveform indicating at least an actual value of a signal of the circuit design in one or more clock cycles; displaying a signal wave overlay on the first waveform in the one or more clock cycles, the signal wave overlay having an appearance corresponding to a specified location and indicating a desired value of the signal in the one or more clock cycles, wherein the desired value is different from the actual value of the signal in the one or more clock cycles; generating a visualization constraint for the circuit design based at least in part on the desired value of the signal indicated by the signal wave overlay; and generating a second waveform for the circuit design that satisfies the visualization constraint.
