11.2 Constraint System - Area group constraint with group setting and compression results in a syntax error

Description

When I attempt to implement a design with an Area Group constraint that includes both group setting and compression, as shown in the example below:

INST "ep" AREA_GROUP = "AG_ep";

AREA_GROUP "AG_ep" COMPRESSION=0 | GROUP=OPEN;

the following error occurs:

"ERROR:ConstraintSystem - In file: pcie_epp_16_top.ucf(2): Syntax error. Ensure that the previous constraint specification was

terminated with ';'."

It appears that the syntax is fine. How can I resolve this issue?

Solution

This issue is currently under investigation. Meanwhile, to work around the problem, modify the Area Group constraint as follows:

AREA_GROUP "AG_ep" COMPRESSION=0;

AREA_GROUP "AG_ep" GROUP=OPEN;

This issue is scheduled to be fixed in the next major release of the software.
