Hi,

@Alex, I agree that it is not the best practice to use the .qsf-file for a new project :) or to edit them... even though I have to admit I do that once in a while when I do bulk changes :rolleyes:

However, then I'd recommend to use the Assignment Export / Import feature of Quartus, at least for the device and pin assignments. These two categories are guaranteed to stay the same, so you can save a lot of work, as the DE0 has hundreds of pins. Here's how:

  • open a sample project that you got from Terasic (the link I posted earlier), or from somewhere else, in Quartus

  • go "Assignments" > "Export Assignments", and save them somewhere

  • create a new project as Alex described

  • go "Assignments" > "Import Assignments", and make sure you only import the categories "Device Assignments" and "Pin & Location Assignments" (button "Categories")

Best regards,
