Board Level Bidirectional Connections

Hello group,

How are two models combined at the board level?

Specifically, I have a Spartan3 with some models
that I have made and connected to the Spartan3
is a NBT SRAM, which I have recently downloaded
a model from the manufacturer's web site. All in VHDL.

And there is relatively short traces from the Spartan3
to the SRAM. The bidirectional ports seem to be an
issue, because I want the Spartan3 to run them, not the
testbench.
