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.
