This means that you:
- Don't have a license and/or don't have your license installed properly.
- Must be "tethered" in order for your FPGA design to function.
After programming your board, in Quartus II, do
not close the window that pops up. This window is a visual representation of a process that runs on your PC to ensure that your non-licensed IP isn't used standalone. On the FPGA, the IP cores that don't have licensing check to see that you're still connected (via your JTAG cable) to the PC. If you disconnect the cable (or close the above-mentioned window), this IP will stop functioning.
Hope that helps!
