D.C. is correct to some degree. There are Spice vendors that support
IBIS. Those vendors are usually SI EDA companies. To that end they do
make behavioral IBIS models and yes they are usually in the specfic
Spice flavor syntax, language etc. However it should be noted that this
is no different than having say Quad models and trying to run those in
Interconnectix. Each Spice vendor has its own merits much like non-spice
vendors. Among those merits may be support of IBIS models. It should
further be noted that other tools developed by acadamia much like spice,
is embraced, enhanced and resold at a handsome price (with enhancements)
of course. So it is not a surprise that Spice vendors would enhance,
modify improve etc. their simulator to better serve their customers.
It would be nice to have a standard but hey isn't that what IBIS
attempts to be?
