I'm trying to run a post-fit simulation for a CAPS design. I'm using Ism in SIS 13.4.
The problem is, I want to instantiate multiple (2 to start with) instances of my design, "connect" them together in the test bench, to see how they interact with one another. The two instances are tutu and tutu.
This seems to work, but I can only get 1 instance to be post-fit. The other seems to only have behavioral timing. The problem may be that in the post-fit simulation settings, you have to specify "Ism OUT Instance Name" - this is set to tutu, but setting it to "tutu, tutu" doesn't work.
Has anyone tried this before, and does anyone have any ideas?
Thanks in advance

ISE should generate a post-fit simulation model with a different name than the original
top level code, but with the same extension - .v for verilog or .vhd for VHDL. If your
test-bench needs to have more than one instance of the post-fit design, you could
make a copy of the post-fit simulation model, give it a different entity or module name,
and explicitly instantiate that one for the second instance (not the "UUT").
