3.3. Specifying the IP Parameters and Options

The Low Latency 40G Ethernet Intel® FPGA IP parameter editor allows you to configure your custom IP variation. Use the following steps to specify IP options and parameters in the Quartus® Prime Pro Edition software.
  1. In the Quartus® Prime Pro Edition, click File > New Project Wizard to create a new Quartus® Prime project, or File > Open Project to open an existing Quartus® Prime project. The wizard prompts you to specify a device.
  2. In the IP Catalog (Tools > IP Catalog), locate and double-click the name of the IP to customize. 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> .ip.
  4. Click OK. The parameter editor appears.
  5. On the IP tab, specify the parameters for your IP variation. Refer to the Low Latency 40G Ethernet Intel® FPGA IP Design Example User Guide: Agilex™ 5 FPGAs and SoCs section for information about specific IP parameters.
  6. Optionally, to generate a simulation testbench or compilation and hardware design example, follow the instructions in the Low Latency 40G Ethernet Intel® FPGA IP Design Example User Guide: Agilex™ 5 FPGAs and SoCs .
  7. Click Generate HDL. The Generation dialog box appears.
  8. Specify output file generation options, and then click Generate. The IP variation files generate according to your specifications.
  9. Click Finish. The parameter editor adds the top-level .ip file to the current project automatically. If you are prompted to manually add the .ip file to the project, click Project > Add/Remove Files in Project to add the file.
  10. After generating and instantiating your IP in the design, make appropriate pin assignments to connect signal ports to external interfaces.
