Description

Available Design Example
Select Design
  • None
  • DisplayPort SST Parallel Loopback with PCR
  • DisplayPort SST Parallel Loopback without PCR
  • DisplayPort MST Parallel Loopback with PCR
  • DisplayPort MST Parallel Loopback without PCR
Select the design example to be generated.
  • None: No design example is available for the current parameter selection
  • DisplayPort SST Parallel Loopback with PCR: This design example demonstrates parallel loopback from DisplayPort sink to DisplayPort source through a Pixel Clock Recovery (PCR) module when you turn off the Enable Video Input Image Port parameter.
  • DisplayPort SST Parallel Loopback without PCR: This design example demonstrates parallel loopback from DisplayPort sink to DisplayPort source without a Pixel Clock Recovery (PCR) module when you turn on the Enable Video Input Image Port parameter.
  • DisplayPort MST Parallel Loopback with PCR: This design example demonstrates parallel loopback from DisplayPort sink to DisplayPort source through a Pixel Clock Recovery (PCR) module when you turn off the Enable Video Input Image Port parameter and turn on the Support MST parameter for TX and RX.
  • DisplayPort MST Parallel Loopback without PCR: This design example demonstrates parallel loopback from DisplayPort sink to DisplayPort source without a Pixel Clock Recovery (PCR) module when you turn on the Enable Video Input Image Port parameter and turn on the Support MST parameter for TX and RX.
Note: Only DisplayPort SST Parallel Loopback with PCR is available in the Intel® Quartus® Prime Standard Edition.
Design Example Files
Simulation

On, Off

Turn on this option to generate the necessary files for the simulation testbench.
Synthesis

On, Off

Turn on this option to generate the necessary files for Intel® Quartus® Prime compilation and hardware demonstration.

Generated HDL Format
Generate File Format

Verilog, VHDL

 Select your preferred HDL format for the generated design example fileset.
Note: This option only determines the format for the generated top level IP files. All other files (e.g. example testbenches and top level files for hardware demonstration) are in Verilog HDL format.

Target Development Kit

Select Board
  • No Development Kit
  • Intel® Arria® 10 GX FPGA Development Kit
  • Custom Development Kit
 Select the board for the targeted design example.
  • No Development Kit: This option excludes all hardware aspects for the design example. The IP core sets all pin assignments to virtual pins.
  • Intel® Arria® 10 GX FPGA Development Kit: This option automatically selects the project's target device to match the device on this development kit. You may change the target device using the Change Target Device parameter if your board revision has a different device variant. The IP core sets all pin assignments according to the development kit.
  • Custom Development Kit: This option allows the design example to be tested on a third-party development kit with an Intel FPGA. You may need to set the pin assignments on your own.
Target Device
Change Target Device On, Off Turn on this option and select the preferred device variant for the development kit.
