Error (12857): HIP reset pin "perst" is locked to "PIN_&ltyour_PERST_ pin location&gt", which is not legal.

Description

Due to a problem in Quartus® II software version 13.1, you will see this error if you incorrectly hook up the DDR3 pins or have unconnected pins in the DDR portion of the device.  If you have such incorrect DDR pin connections you will see this error even if your PERST is on a legal and correct pin location.

Resolution

Correct the DDR pin errors.

This problem is fixed in Quartus II software version 14.0.
