2.11. Transceiver Lane Configurations

If you want to configure your design to use 1, 2 or 4 lanes targeting different versions of Bitec FMC daughter cards, you have to configure the pin assignments accordingly in the Quartus® Prime Pro Settings File (QSF).
To configure the DisplayPort Intel® FPGA IP design example using 1, 2 or 4 lanes, follow these steps:
  1. In both the DisplayPort Source and Sink parameter editors, set the Maximum lane count parameter to 1, 2 or 4.
  2. Generate the design example.
  3. Make the following assignments in the Assignment Editor.
