Error: Could not find location for HSSI PMA RX Buffer that satisifes the VCCR_GXB/VCCT_GXB Voltage requirement of 1_1_V (1 location affected)

Due to a bug in the Quartus® II software version 12.0 SP2 and earlier you may see this error using Arria® V GX devices.

If your design has more than one transceiver instance where some are configured for a datrarate greater than 3125Mbps, and some less than 3125Mps, the Quartus software is unable to resolve the required VCCR_GXB and VCCT_GXB voltage requirements.

To fix this problem in Quartus II 12.0 SP2 install the appropriate patch 2.06 below.

• Quartus II software version 12.0 SP2 patch 2.06 for Windows (.exe)
• Quartus II software version 12.0 SP2 patch 2.06 for Linux (.tar)
• Quartus II software version 12.0 SP2 patch 2.06 Read Me file (.txt)

This issue will be fixed in a future version of the Quartus II Software.
