Hello,
I am simulating an ibis file using HSPICE. I will be thankful to you if
anyone of you can help me in the following queries:

(a) While simulating an ibis buffer model of I/O type in the input mode,
i.e. when the signal from external world appears on the pad, the high
level output of input buffer is always 1V regardless of any other factor.
Why is it so ?

(b) Why if while using the I/O buffer in input mode I have to specify the
input for the output buffer, which is of no use to me, otherwise it gives
an error that no voltage sources are defined.

Thank you in anticipation
Regards
Rajesh Kaushik
