Re: Bird 36.2

Stephen,

I do not see any accomodation of series pass elements
in the path structure for this specification. Many memory
modules, MCM's, and boards utilize series resistors and/or
more complex filtering structures. It is important to be
able to model them explicitly, since they are actual components,
rather than a degenerate case of the transmission line
descriptor.
