Is it possible to use Virtual JTAG and SignalTap at the same time?

I've added VJTAG to my project so I can send commands to my FPGA from the command line using a TCL script - commands such as "write to address x with value y" or "get value from address x".

This is great but I need to be able to see what is happening inside with SignalTap.

Is it possible to use SignalTap in conjunction with a TCL script and VJTAG? At the moment it seems as though I can only run one or the other.

    @SyafieqS I would say "no", it is not possible. I managed to get around this by:

    1) using quartus_stp.exe/TCL scripts to pre-load test parameters

    2) stop quartus_stp.exe

    3) connecting SignalTap

    4) execute test by pressing a button

    5) viewing SignalTap output upon triggering

    Paul,


    May I know if there is any update?


    I would say it is not possible since both are On-Chip Debugging Tool and circumstance use is different from one to another
