The 1G/2.5G Ethernet PCS/PMA or SGMII solution delivers files into several filegroups. By default the filegroups necessary for use of the core or opening the IP example design are created when the core is generated. If additional filegroups are required these can be selected using the generate option. The filegroups generated can be seen in the IP Sources tab of the Sources window where they are listed for each IP in the project. The filegroups available for the 1G/2.5G Ethernet PCS/PMA or SGMII solution are described in the following subsections.
