I am using Quartus 22.1 Lite software. I has been working fine until I try to set the Signal Tap Trigger flow control to "State-base". When I set it to State-base instead of Sequential, the entire ...

When you choose Signal Tap from the Tools menu, assuming your project is already open, that's opening the existing .stp file for your project, so you are in a .stp at that point. Everything you do in Signal Tap is in a .stp file.

Go to the File menu -> New in Quartus to create a brand new .stp. See if you still have the issue there.

    This all happens when Quartus is opened and then Signal Tap is opened without opening a project. Hence, there is no active *.stp file at the time of the crash. The sequence of events is:

    1. Open Quartus

    2. Open Signal Tap

    3. Change the "Trigger Flow Control" box to State-Based

    4. Crash

    It also happens in the same way if a project is open with an active *.stp file. Like I said previously 20.1.1 Lite works and both 21.1 and 22.1 Lite crash.

    Any ideas??
