Have you tryed the -u option in the mapping stage? I include the -u
description. Regards Andres –u (Do Not Remove Unused Logic) By default (without the –u option), MAP eliminates unused components and nets from the design before mapping. If –u is specified, MAP maps unused components and nets in the input design and includes them as part of the output design. The –u option is helpful if you want to run a preliminary mapping on an unfinished design, possibly to see how many components the mapped design uses. By specifying –u, you are assured that all of the design’s logic (even logic that is part of incomplete nets) is mapped. jcastillo wrote: I have it done as you mentioned, but the problem is not with the synthesizer, Leonardo and Synplify mapped the ICAP module as a black box. The problem is inside ISE in the mapping stage. The mapper detects that the ICAP module has no outputs connected to pins and trimmed it.

Then the black box is for the static module and not only for the ICAP. I dont know whether it works, because I do it with three modules in the fixed part of my design, but i not used the ICAP module. JOHN ESQUIAGOLAHi, I have a problem with ICAP, I instantiate and give it the attribute syn_noprune with Synplicity because since it has no outputs, the synthetizer trimmed it. With this attribute I have the edf file with ICAP as a black box. But when ISE maps the design it trimmed ICAP module because it has no outputs connected pins. Is there a way to solve this problem?
