Waveform
A graphical representation of signal values over time, used for debugging and analyzing circuit behavior.
Detailed Explanation
Waveform viewers display simulation results as time-varying signals. Digital signals show high/low/unknown/high-Z states. Analog signals show continuous values. Cursors measure timing relationships. Waveform databases can be huge for long simulations.
Waveform debugging involves finding unexpected transitions, checking timing relationships, and tracing signal sources. Hierarchical navigation helps locate signals in complex designs.
