Aurora IP provides Block Automation in the IP integrator to enable IP to connect to GT
Wizard seamlessly. IP Block Automation instantiates GT Wizard and creates essential
datapath, USRCLK and GT REFCLK connections. The number
of GT Quads required in the wizard are calculated depending on number of aurora
lanes.
Perform the following steps to connect multiple Aurora IPs using Block Automation:
- Add Aurora 64B66B IP using Add IP option in the IP integrator canvas.
- Configure Aurora 64B66B IP for number of lanes, line rates, and so on.
- Click
Run_Block_Automation. In the Block Automation GUI, the automation always instantiates new wizard for each aurora in IP integrator canvas.
GT Wizard parameters are propagated from its connected IPs when the design is validated. Hence, all parameters are marked Auto in the Transceiver Wizard GUI. However, you can change the Auto option to Manual for Transceiver Configurations 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 Wizard parameters from parent IP to GT Wizard. Manual changes should only be performed after all essential parent IP parameters are propagated to GT Wizard.
