Description
The Intel Stratix 10 and Intel Agilex device E-Tile receiver requires incoming data in order for the RX Adaption algorithm to work. You also cannot run the PRBS verifier at the same time as the RX Adaption algorithm in the Transceiver Toolkit.
Resolution
To initialize your Intel Stratix 10 and Intel Agilex device E-Tile transceiver channels in the Intel Quartus Prime software Transceiver Toolkit, you should use the following sequence.
- Select the TX and RX PHY and switch on internal serial loopback
- Select the TX and RX PHY and set the PRBS pattern to PRBS31
- Select the TX PHY only and start the Hard PRBS Generator
- Select the RX PHY only and run Initial Adaption and wait for it to finish
- Select the RX PHY only and start the Hard PRBS Verifier. You should have error free internal serial loopback data. You can reset the PRBS Verifier if necessary.
- Select the RX PHY only and stop the Hard PRBS Verifier
- Select the TX and RX PHY and switch OFF internal serial loopback. This assumes that you have external loopback, or incoming traffic.
- Select the RX PHY only and run Initial Adaption and wait for it to finish
- Select the RX PHY only and start the Hard PRBS Verifier. You should have error free external serial loopback data or traffic. You can reset the PRBS Verifier if necessary.
