I am using Quartus II so I don't know if this is an issue with Quartus Prime or not. I can use the sources and probes megafunction, and read and write to the data values, but to make this useful, you have to group and rename the signals. After configuring groups and names, I can save the setup to a ".spf" file, but I can't find a way to read the file back in the next time I use the tool. Anyone been able to figure this out? Also, is there a TCL was to accomplish the same thing?
What do you mean by reading the file back in? Just program the device and reopen the .spf file, or program the device directly from the .spf file.
