I have a simulation that generate a zero-width pulse. There are two waveform file. One is vcd. Another one is shm. Both waveform was dump in same time. When i using Simvision to open both waveform, the VCD waveform file show the icon of zero-width pulse on waveform. But the SHM wavefrom file doesn't show it.
How can I set the Simvision showning the zero width icon?
The yellow icon should have showed up in the shm database too. I am not sure why it isn't.
You can dump event based waveforms. This will help in catching any glitches that might be generated from within the design.To dump the delta events you need to use the following TCL commands:ncsim> database -open waves -shm -default -eventncsim> probe -create -shm -all -depth allYou can issue the above commands at the ncsim TCL console BEFORE running the simulation/sending signals to waveform window or you can put them in a file called input.tcl and provide this file to irun/ncverilog with -input option.> irun -input input.tcl <other options>To expand the time sequence: Go to the "Simvision Waveform WIndow" Go to "View" menu Go to "Expand Sequence Time" Go to "All Time"
