Aurora IP provides Block Automation in the IP integrator to enable IP to connect to GT Quad seamlessly. IP Block Automation instantiates GT Quads and creates essential datapath, USRCLK, and GT REFCLK connections.

Perform the following steps to connect multiple Aurora IPs using Block Automation:

  1. Add Aurora64B66B IP using Add IP option in the IP integrator canvas.
  2. Configure Aurora64B66B IP for number of lanes, line rates, and so on.
  3. Click Run_Block_Automation. In the Block Automation GUI, select one of the options Auto, Start_with_New_Quad, or Customized_Connections.

  4. Perform Steps 2 and 3 to add more Aurora64B66B IP instances based on your system need.

GT Quad parameters are propagated from its connected IPs when the design is validated. Hence, all GT Quad parameters are marked Auto in the Transceiver Wizard GUI. However, you can change the Auto option to Manual for Transceiver Configs as shown in the following figure to fine-tune parameters like insertion loss, drive strength, equalization, and other advanced settings.

After toggling to Manual mode, any changes to the parent IP configurations followed by validation no longer propagate GT Quad parameters from the parent IP to GT Quad. Manual changes should only be performed after all essential parent IP parameters are propagated to GT Quad.
