A simple question (I specialize in those): why are we prohibited from using
Model_type Terminator and [Algorithmic Model] together? The specification
explicitly limits Terminator to input buffers, but that should only prevent
using the Model_type with transmitters. Wouldn't Terminator be a pretty
friendly way of modeling receiver buffer analog impedances? Nevertheless,
Terminator is explicitly prohibited from use as a Model_type with [Algorithmic
Model].
The parser (IBISCHK5, 5.1.2) correctly yields the following for such a
combination:
ERROR - Algorithmic Model is not allowed for model modelname which is of type
Terminator.
There's a related issue that there's no way to check whether I am combining a
transmitter-only [Algorithmic Model] with an input or Terminator Model_type,
but that's a separate problem.
Is it time for a BUG and a BIRD?
