Simulation problem: unwanted zero-width glitch

ridgemao
I'm using LDV 5.1. In simvision's waveform window, many signals have zero-width glitch. How can I avoid displaying these glitches? I know it is due to the zero-time delay of sequential logic in functional simulation, and these "zero-width glitch" won't appears in actual application because there is no zero-time delay in actual sequential logic. And I think the simulator knows all about it and It marks the "zero-width glitch" with a special sign. I don't want the simulator to display these glitches, how can I make it? Thanks.

  • As a side-note, sometimes one sees behavior that seems inexplicable, such as a flip-flop whose output changes although its data input looks constant all the time. In such cases, one should suspect a zero-width glitch and turn on -event. I had such a case just recently.
