Triple Speed Ethernet Design Fails in Fitter with Internal Error for Arria V Device


The triple speed ethernet design channel_8_mac_pcs_gxb_arriav fails with internal error during the Quartus II compilation process. The failure is caused by the fitter failing to read pins with certain seed values.

This issue affects Arria V devices with the following design:

Device family: Arria V

Device: 5AGXFB7K6F40C6

IP: Triple speed ethernet

Variant: 10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII PCS

No internal FIFO

8 Ports

Use transceiver block, GXB

Include MDIO module

Enable SGMII bridge


Re-run the Quartus II compilation process with a different seed value.

This issue will be fixed in 13.0.
