Subject: [IBIS-Users] Using the '.ibis' (note the dot) in HSPICE

I have spent the last 2 days puzzling over how to use the ' .ibis ' call in
hspice.
Using the basic ibis buffer works ok, but this other command was there to
try as well.
The ibis device I have is a basic TS TTL buffering device that says it is
2.1 compatible.
When hspice runs I can see that it allocates a buffer to each input and
output pin.
However, the stim I put on the input pin does not get propagated to the
output pin.
I can see the input buffer switching a-ok, but the output buffer does not.
I have even tried different enable pin values to see if that had an effect.
What seem to be missing is the 'hook' to drive the output buffers nd_in
port.
Actually, I do not even see a port named nd_in for the output buffers. I
can
see the pc and pd and en pins OK though.
Can someone shed some light on my confusion?
thanks,
Mike Dotson
