FPGA Express 3.3: Converting Constraints (.EXC) to ASCII or TCL and adding Constraints to
the FE_SHELL
Problem Description:
Urgency: Standard
General Description:
Is It possible to Export the details entered into the Express Constraints Editor to an ASCII
or TCL and then adding constraints to the FE_SHELL area?
Solution 1:
There is no way to export the details of constraints entered in the Constraints Editor to an
ASCII or TCL format. The only way to save it is in the binary .EXC format. However, you
can load that file for a synthesis run in TCL by using the import_constraint command.
You can also do most of the things that you can do in the Constraints Editor with the FE_SHELL
area. For help on FE_SHELL commands, open FE_SHELL and type "help". You can get
detailed help by typing "man <command>" for any command listed by help. Currently there is
no way to convert the information in the .EXC into TCL-based commands.
