When I re-initialize simulation, signals disappeared from my existing waveform window. How can I keep list of those signals?
The standard waveform and accelerated waveform have different architecture and hence different ways to operate.
Select the Preserve signals when simulation is initialized checkbox on the Waveform Preferences/Behavior - advanced tab.
To invoke the Waveform preferences dialog
Go to Tools | Preferences... dialog box,
Select Editors | Waveform Viewer/Editor | Accelerated Waveform Viewer category
Click the Options... button. When enabled, previously added signals are not removed from the Accelerated Waveform at the initialization of simulation.
Once you have all the signals of interest on the waveform and with waveform open, goto Waveform > Save to macro
A .do macro will be created with all the signals you dragged in the waveform
Next time you initialize the sim > make sure to right click on the .do file in design browser > Execute and all signals will appear on your waveform
4. You can edit the .do macro if you want to add more signals/ remove existing signals.
