When i add these 2 constraint to my UCF file: CONFIG POST_CRC = "ENABLE"; CONFIG POST_CRC_SIGNAL = "FRAME_ECC_ONLY";
I get these error messages while doing the timing driven packing phase in the map command.
ERROR:Place:911 - CONFIG POST_CRC = ENABLE is not a valid constraint. ERROR:Place:911 - CONFIG POST_CRC_SIGNAL = FRAME_ECC_ONLY is not a valid constraint.
The ngdbuild phase had 0 warnings and errors so i have no indications what could be the problem.
Thankful for any suggestions.
