This is an old thread, but I thought I would add to the IBIS
simulation algorithm literature. An IEEE sponsored conference had
the following paper:
"The Development of Analog SPICE Behavioral Model Based on IBIS Model",
Proceedings of the Ninth Great Lakes Symposium on VLSI, March, 1999,
Ying Wang and Han Ngee Tan of Nanyang Technological University,
Singapore, pp. 101-104.

can be downloaded:
