For Agilex™ 7, Agilex™ 5, Stratix®, Arria® 10, and Cyclone® 10 GX devices, use the DisplayPort FPGA parameter editor in the Quartus® Prime Pro Edition software to generate the design example.

1. Click Tools IP Catalog, and select target device family.
2. In the IP Catalog, locate and double-click DisplayPort FPGA IP. The New IP Variation window appears.
3. Specify a top-level name for your custom IP variation. The parameter editor saves the IP variation settings in a file named ip.
4. You may select a specific FPGA device in the Device field, or keep the default Quartus® Prime software device selection.
5. Click OK. The parameter editor appears.
6. Configure the desired parameters for both TX and RX.
7. On the Design Example tab, select the design example that fits your criteria.
8. Select Simulation to generate the testbench, and select Synthesis to generate the hardware design example. You must select at least one of these options to generate the design example files. If you select both, the generation time is longer.
9. For Target Development Kit, select the available FPGA development kit. If you select the development kit, then the target device (selected in step 4) changes to match the device on the development kit.
10. Click Generate Example Design.

My design require Bitec FMC daughter card. How do I select them?

The following table provides a quick guideline in selecting Bitec FMC daughtercard revision.

Any requirement to use single or dual lanes transceiver channel with Bitec FMC daughter card for 10-series devices?

Yes. For DisplayPort design that uses/referred to in an early version of Bitec FMC daughtercard (revision 8 and earlier), the pin assignment in the following link has to be followed at TX and RX due to the lane reversal and polarity inversion at the channel.

How do I create a DisplayPort TX-only or RX-only design?

A general guideline to create a DisplayPort TX-only or RX-only design can be found in the DisplayPort Arria® 10 FPGA IP Design Example User Guide.
