11.x ISE - When running "Translate" in Project Navigator, the NGDBuild "-i" option is used even if UCF is added to the sources

Description


When UCF has been added to sources in Project Navigator, the "-i" option is applied to NGDBuild if you check the NGDBuild command line in .cmd_log or .bld files after running Translate.



Why is the "-i" option used? Is the UCF really ignored?

Solution


The UCF is not ignored. The "-i" option cooperates with "-ise" to make sure that the constraints in UCF are applied to the design correctly. This is the intended behavior of Project Navigator.



If you are using the .cmd_log file to create command line script, you need to remove both "-ise" and "-i" options and add "-uc" if necessary.
