Unfortunately my thread from the old forum was lost on this subject but here goes off the top of my head.

  • Check your top level connectivity for issues (like dangling nets or signals pulled high or low)

  • Check your pinout to make sure you are using the correct I/O in your design

  • If you are using the new "Altera ALTPLL" component don't use the PLL lock signal as a filter for reset_n (you'll get stuck in reset). This will be fixed in the next version of the IP.

If I think of other things to check I'll add them.
