User guide

Before you begin
You should be familiar with the Standard PCS and PMA architecture, PLL architecture, and the reset
controller before implementing the GbE protocol.
1. Instantiate the Arria 10 Transceiver Native PHY IP from the IP Catalog.
Refer to Select and Instantiate the PHY IP Core on page 2-2.
2. Select GbE or GbE 1588 from the Transceiver configuration rules list located under Datapath
Options, depending on which protocol you are implementing.
3. Use the parameter values in the tables in Native PHY IP Parameter Settings for GbE and GbE with
IEEE 1588v2 on page 2-106 as a starting point. Or, you can use the protocol presets described in
Presets. You can then modify the setting to meet your specific requirements.
4. Click Generate to generate the Native PHY IP core top-level RTL file.
Figure 2-36: Signals and Ports for Native PHY IP Configured for GbE or GbE with IEEE 1588v2
Generating the IP core creates signals and ports based on your parameter settings.

Note:
1. rx_rmfifostatus is not available in the GbE with 1588 configuration.
5. Instantiate and configure your PLL.
6. Instantiate a transceiver reset controller.
