Simulation and Verification

I'm using ISE 13.2 and I'm trying to use the -incremental flag for fuse, but it seems to me that it is not working. It will, for example, recompile my gtp ip-core everytime, eventhough it doesn't change between runs. And it takes quite a while to compile.

Does anyone else have the same problem?

My command line is:

Running: C:\Xilinx\13.2\ISE_DS\ISE\bin\nt64\unwrapped\fuse.exe -lib secureip -incremental -nodebug -o isim/isim_tb.exe -prj isim.prj --rangecheck work.du_interface_tb

fuse must have become more conservative in release 13.x

Using 12.1 I have the opposite problem.  I find that if I use the -incremental switch fuse

will not recompile after I change my test bench unless some underlying modules are

also updated.  So normally I turn this off.  Inability to figure out what needs to be recompiled

seems to be a recurring theme in the ISE tools.

Okay, thanks!

I'm having a somwhat hard time to understand how this could be that difficult to fix. Looks like they simply disabled the -incremental flag for now, but why not mention it then? I haven't been able to find anything about it in the docs.
