2.7.1. Pin Assignments

When you integrate your LL 100GbE IP core instance in your design, you must make appropriate pin assignments. You can create a virtual pin to avoid making specific pin assignments for top-level signals until you are ready to map the design to hardware.

For the Arria 10 device family, you must configure a transceiver PLL that is external to the LL 100GbE IP core. The transceiver PLLs you configure are physically present in the device transceivers, but the LL 100GbE IP core does not configure and connect them. The required number of transceiver PLLs depends on the distribution of your Ethernet data pins in the different Arria 10 transceiver blocks.
