Example application using the Triple-Speed Ethernet MegaCore function with 1000BASE-X and PMA. The
PMA block connects to an off-the-shelf GBIC or SFP module to communicate directly over the optical link.

Serial Bridge Mode
Example application using the Triple-Speed Ethernet MegaCore function with 1000BASE-X and PMA, in
which the PCS function is configured to operate in SGMII mode and acts as a GMII-to-SGMII bridge. In
this case, the transceiver I/O connects to an off-the-shelf Ethernet PHY that supports SGMII (10BASE-T,
100BASE-T, or 1000BASE-T Ethernet PHY).

MegaCore Verification
For each release, Altera verifies the Triple-Speed Ethernet MegaCore function through extensive simulation
and internal hardware verification in various Altera device families. The University of New Hampshire
(UNH) InterOperability Lab also successfully verified the MegaCore function prior to its release.
Altera used a highly parameterizeable transaction-based testbench to test the following aspects of the
MegaCore function:
