Part 2.9: Board to Board Connectors pin assignment

The core board has a total of two high-speed board to board connectors.
The core board uses two 80-pin inter-board connecters to connect to the
Carrier Board. The IO port of the FPGA is connected to the two connecters by
differential routing. The pin spacing of the connectors is 0.5mm, insert to the
board to board connectors on the Carrier Board for high-speed data
communication.
