3.4.2. Generate the Design

Use the DisplayPort Intel® FPGA IP parameter editor in the Intel® Quartus® Prime Pro Edition software to generate the design example.
Before you begin, ensure to install the HDCP feature in the Intel® Quartus® Prime Pro Edition software.
Note: The HDCP feature is not included in the Intel® Quartus® Prime Pro Edition software. To access the HDCP feature, contact Intel at https://www.intel.com/content/www/us/en/broadcast/products/programmable/applications/connectivity-solutions.html.
  1. Click Tools > IP Catalog, and select Intel Agilex® 7 as the target device family.
    Note: The HDCP design example supports only Intel® Arria® 10, Intel® Stratix® 10, and Intel Agilex® 7 devices.
  2. In the IP Catalog, locate and double-click DisplayPort Intel® 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 <your_ip>.qsys.
  4. You may select a specific device in the Device field, or keep the default software device selection.
  5. Click OK. The parameter editor appears.
  6. Configure the desired parameters for both TX and RX
    Note: To enable the HDCP feature on RX, turn on the Enable GPU Mode parameter.
  7. Turn on Support HDCP Key Management parameter if you want to store the HDCP production key in an encrypted format in the external flash memory or EEPROM. Otherwise, turn off this parameter to store the HDCP production key in plain format in the FPGA.
  8. On the Design Example tab, select DisplayPort SST Parallel Loopback Without PCR.
  9. Select Synthesis to generate the hardware design example.
  10. For Target Development Kit, select Agilex 7 I-Series SOC 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. For Agilex I-Series SoC Development Kit, the default device is AGIB027R31B2E2VR0.
  11. Click Generate Example Design to generate the project files and the software Executable and Linking Format (ELF) programming file.
