2.6.1. Pin Assignments

When you integrate your 50G Interlaken IP core instance in your design, you must make appropriate pin assignments. You do not need to specify pin assignments for simulation. However, you should make the pin assignments before you compile, to provide direction to the Quartus Prime Fitter and to specify the signals that should be assigned to device pins.

You can create a virtual pin to avoid making specific pin assignments for top-level signals while you are simulating and not ready to map the design to hardware. Do not create virtual pins for clock or Interlaken link data signals.

For the Intel® Arria® 10 device family, you must configure a PLL external to the 50G Interlaken IP core. The required number of PLLs depends on the distribution of your Interlaken lane data pins in the different A10 transceiver blocks.
