Waveform viewer
A waveform viewer is a software tool for viewing the signal levels of either a digital or analog circuit design. Waveform viewers comes in two varieties: simulation waveform viewers for displaying signal levels of simulated design models, and in-circuit waveform viewers for displaying signal levels captured in-circuit while debugging or testing hardware boards (see also waveform monitor) == Simulation waveform viewers == In integrated circuit design, waveform viewers are typically used in conjunction with a simulation.
