Design constraints affect how the logical design is implemented in
the target device. Applying constraints helps you to adapt your
design’s performance to expected worst-case conditions. The user
constraint file (.ucf) is an ASCII file that holds timing and location
constraints. It is read (by NGDBuild) during the translate process in
the Flow Engine and is combined with an EDIF or XNF netlist into an
NGD file.
Each revision contains an associated UCF file. The UCF file may be a
default (empty) UCF or one that you customize yourself. You can
directly enter constraints in the UCF file through a text editor or you
can use the Xilinx Constraints Editor.
1.
Click Run to implement the design. The Flow Engine displays the
progress of the implementation.
The Project Manager displays a status message when Implemen-
tation is complete. View the Console tab on the Project Manager
window for the results of all stages of the implementation. The
Versions tab also indicates the status of the implemented revi-
sion.
To view design reports, select the desired revision in the Versions
tab of the Project Manager. Then select the Reports tab in the
Project Manager Flow window.
Click on the Implementation Report Files icon to view the imple-
mentation reports. Click on the Implementation Log File icon to
view the Flow Engine’s processing log.
For more information on the Flow Engine, select Help

The Constraints Editor is a Graphical User Interface (GUI) that
you can run after the Translate program to create new constraints
in a UCF file. To access the Constraints Editor, select Tools
Implementation

The following figure shows an example of the Global tab of the
Implementation Constraints Editor.
