altgx Megafunction

High-Speed Serial Interface (HSSI) gigabit transceiver block (GXB) Definition megafunction. The altgx megafunction enables dedicated circuitry on supported device(Arria series, Cyclone IV, and Stratix IV) families.

The altgx megafunction must be instantiated with the IP Catalog.

Note:

For this megafunction, the IP Catalog generates output files with multiple entities or modules. The top-level entity or module is located at the bottom of the file.
When you create your megafunction, you can use the IP Catalog to generate a netlist for third-party synthesis tools.
