Performance and Resource Utilization
This section describes performance and resource utilization for the IP core.
Because the Standard PCS and PMA are implemented in hard logic, the Arria V Native PHY IP Core
requires minimal resources.
Parameterizing the Arria V Native PHY
By default, the Arria V Native PHY Transceiver PHY IP defaults to the PMA direct datapath and an
internal PLL. You can change the default configuration to include the PCS or an external fractional PLL.
1. Under Tools > IP Catalog, select Arria V as the device family.
2. Under Tools > IP Catalog > Interface Protocols > Transceiver PHY, select Arria V Native PHY.
3. Use the tabs on the MegaWizard Plug-In Manager to select the options required for the protocol.
4. Click Finish to generate your customized Arria V Native PHY IP Core.
Note: The Arria V Transceiver Native PHY provides presets for CPRI, GIGE, and the Low Latency
Standard PCS. The presets specify the parameters required to the protocol specified.
General Parameters
This section lists the parameters available on the General Options tab.
