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?
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.
