Xcelium: How to Enable Delta Events on Wave

Glitch in simulation
 
How do we enable delta events on waves in Xcelium?
 
To enable the delta events following TCL commands:
xcelium> database -open waves -shm -default -event
xcelium> probe -create -shm -all -depth all
 
Commands need to be typed in the Xcelium console before running the simulation.
 
Another option is to put them in a TCL file and provide this file to irun/ncverilog with -input option. xcelium> -input wave_setup.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”
 
 Delta events are shown on waveforms like this:
When we zoom in we will see a blue area with multiple delta events.
