14.3 PlanAhead - "ERROR:MapHelpers:151 - Error while processing the area group range."

Description

I generate the area_group constraint in the PlanAhead tool, such as:

INST "FILL" AREA_GROUP = "pblock_FILL";
AREA_GROUP "pblock_FILL" RANGE=IDELAY_X1Y85:IDELAY_X1Y328, IDELAY_X1Y25:IDELAY_X1Y72, IDELAY_X0Y25:IDELAY_X0Y328;
AREA_GROUP "pblock_FILL" RANGE=ILOGIC_X1Y85:ILOGIC_X1Y328, ILOGIC_X1Y25:ILOGIC_X1Y72, ILOGIC_X0Y25:ILOGIC_X0Y328;
AREA_GROUP "pblock_FILL" RANGE=ODELAY_X1Y85:ODELAY_X1Y328, ODELAY_X1Y25:ODELAY_X1Y72, ODELAY_X0Y50:ODELAY_X0Y328;
AREA_GROUP "pblock_FILL" RANGE=OLOGIC_X1Y85:OLOGIC_X1Y328, OLOGIC_X1Y25:OLOGIC_X1Y72, OLOGIC_X0Y25:OLOGIC_X0Y328;

But in the map stage, the following error occurs:

ERROR:MapHelpers:151 - Error while processing the area group range. Unable to
create a LOC object using the constraint
IDELAY_X1Y85:IDELAY_X1Y328,IDELAY_X1Y25:IDELAY_X1Y72,IDELAY_X0Y25:IDELAY_X0Y3
28 attached to area group pblock_FILL. One or more ranges contain syntax
error or illegal site. Please modify the constraint.

Is there a syntax error?

Solution

It is not a syntax error, however, the PlanAhead tool is not reading the constraint correctly.

You can work around this issue by changing the constraints to remove the IDELAY constraints.

The error is no longer issued in PlanAhead 14.4.
