Quartus

dataout pin <name> of HSDI transmitter fed by PLL <name> is assigned <name> I/O standard but dataout pin <name> of another HSDI transmitter fed by the same PLL is not assigned the same I/O standard

CAUSE: You assigned the HyperTransport I/O standard to the specified dataout pin of an HSDI transmitter that is fed by the specified PLL. However, the same PLL also feeds the specified dataout pin of another HSDI transmitter which is not assigned the same I/O standard. All dataout pins of HSDI transmitters fed by the same PLL must be assigned the HyperTransport I/O standard if at least one dataout pin is assigned the HyperTransport I/O standard, because the HyperTranport IO standard has a different VCCIO voltage than other differential I/O standards.
ACTION: Delete the HyperTransport I/O standard assignment from the specified pin, or assign the HyperTransport I/O standard to all dataout pins of HSDI transmitters fed by the same PLL.
