INSERT IBIS FILE DEMONSTRATING THE BUG:

|****************************************************************
[IBIS Ver]   4.2
|
| With ibisck6 Version 6.1.2 and earlier, No Errors are reported.
| However, with ibischk6 Version 6.1.3, E0275 is reported for
| port name "A_In" not being a reserved name.  This should
| NOT be an error for [External Circuit]s.  This is a change
| in parser functionality.

| According to pg. 123 of the v6.1 IBIS specification, the
| "A_In" port name in the example above should be legal:
|
| "[External Circuit] allows any number of ports to be defined,
| with any names which comply with Section 3 format requirements.
| Reserved port names may be used, but ONLY DIGITAL PORTS will
| have the pre-defined functions listed in the General Assumptions
| heading above. User-defined and reserved port names may be
| combined within the same [External Circuit]."
|
| It appears that the parser only allows reserved port names, as
| shown in the following example:
