Simulation to study the behavior of a design before
prototyping has become an inevitable part of the system
designing. Modeling in turn provides the system
designers with the tool to do the simulation. Spice
simulation has long been the primary method for system
and circuit analysis and design. However, it suffers from
some practical realities such as different simulators,
undocumented simplifications, simulation speed, model
availability, etc. Most importantly, to get the best models
for the spice simulation very often clashes with the issue
of proprietorship of the semiconductor vendors to the
point that the semiconductor manufacturers are reluctant
to provide the spice model of I/O structure to the public,
thus rendering the spice-based models a weak link when
design complexity increases. This issue has been
resolved with the adoption of IBIS as a new standard for
modeling [1,2].
