Hello,
I'm trying to set up a simulation testbench using the HDL Bencher
in ise 4.2i (I have to use that old software, as I am using 5 V
original Spartan chips). It seems that bidirectional buses
can be checked for results, but can't be forced! It displays
with yellow background (inactive) and I've found no way to drive
the bus from the testbench (make it go to blue background or active).
What am I missing here? The manual, even an additional one I downloaded
from the Xilinx web site, was pretty sketchy. Otherwise, it is a really
nice tool for setting up a testbench.
Thanks in advance for any pointers on this.
