Discussion:
Mike LaBonte responded to Bob's request about bugs. Mike commented on BUG228
message. The message does not tell line number of the wrong text. Also, it does
not specify if the error is in the EMD or IBS file. Neither issue is severe,
but both would be nice to include in the error message. Changing the message
text would requre a complete new version of the parser with associated testing.

There is a new BUG238 from Michael regarding incorrect [Interconnect Model]
errors. The file syntax is actually correct, so the errors from the parser
should not be issued. The issue is using the same node name in different
interconnect models in the same set. If the node names are equal in different
model calls the parser issues an error. The specification states that these
nodes are simply connected. The error might be changed to a caution so the
model author can double-check the intended connectivity. Bub suggests in the
BUG report changing the ERROR to CAUTION and editing the error message to
clarify "identical pin_names." [AR] Bob will submit the BUG report to the open
forum for classification. The group had a long discussion about possible usage
of interconnect models with possible parameter passing to easily create
variations of interconnect. The solution is probably to create a BIRD from the
interconnect task group.
