Is PHY Loopback supported using the Triple Speed Ethernet IP in Cyclone® V or Arria® V devices? - Is PHY Loopback supported using the Triple Speed Ethernet IP in Cyclone® V or Arria® V devices? Description Serial Loopback is not supported in Arria® V or Cyclone® V devices with GX transceivers. The Triple Speed Ethernet (TSE) user guide states that "The serial loopback option is not supported in Stratix® V and Cyclone® IV devices with GX transceiver." Resolution Details regarding Arria® V and Cyclone® V devices haven't yet been included in the TSE user guide. This paragraph will be updated to state that Arria® V and Cyclone® V devices do not support PHY Loopback, either.
