Foundation Series 2.1i User Guide
Setting Control Files
11-12
User Constraints File
You can designate a user constraints file, guide files, or Floorplan files
to control the current implementation. You can set the control files
from the Project Manager’s Implementation pulldown menu or via
the Control Files Set button on the Synthesis/Implementation dialog
box.
User constraints files (design_name.ucf) contain logic placement and
timing requirements to control the implementation of your design.
Refer to the “Foundation Constraints” appendix for detailed informa-
tion on creating .ucf files and on constraint syntax.
If you want to control the implementation of your design with a user
constraints file, you can specify this file in the Set Constraints File
dialog box. The software implements your design to meet the speci-
fied timing requirements and other constraints specified in this file.

In the Project Manager, select Implementation
Constraints File(s) to open the dialog box shown in the
following figure.
Make sure Copy Constraints Data From is selected.
In an HDL Flow project, click OK on the Options dialog box to
close it and return to the Synthesis/Implementation dialog
box. Click Run on the Synthesis/Implementation dialog box
to start the Flow Engine. (Refer to the “HDL Flow Projects” -
