How can I keep list of those signals? Solution 1 The standard waveform and accelerated waveform have different architecture and hence different ways to operate. If you are using the accelerated waveform: 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. Solution 2 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. Previous article Next article
