Hi I'm trying to add new/more signals to signal tap analyzer, they are showing up in Node finder but couldn't insert them to stp file. Nothing happens when I click on insert. I'm using Quartus 21.1 pro edition.
So you've opened the Node Finder, found the signals you want to add, used the arrows to move them over to the list on the right, clicked insert, and they simply don't appear in the Node list?
Are you using the Signal Tap filters in the Node Finder? If you don't use those filters, there's no guarantee that the signals you're adding are "tappable" by the logic analyzer.
