RE: [partial-reconfig] ICAP trimmed

["jcastillo" <jcastillo@xxxxxxxxxxxxx>]

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.

Hi Javier,

I think that you can try instantiate the static module(ICAP module and
other logic) in one file. 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.
