Solution

This error occurs because multiple RANGE attributes are accidently being applied to a single AREA GROUP because of a naming conflict.

For example:

INST "INST_NAME1"..................................AREA_GROUP = "GROUP_NAME";
AREA_GROUP "GROUP_NAME"...............RANGE = CLB_R1C60:CLB_R7C72;


INST "INST_NAME2"..................................AREA_GROUP = "GROUP_NAME";
AREA_GROUP "GROUP_NAME"...............RANGE = CLB_R8C60:CLB_R48C72;

We are investigating this error with regards to improving the error handling of range constraint processing.

Meanwhile, avoid the problem can by ensuring that each AREA GROUP only has a single RANGE attribute applied to it.
