We (internally)have a growing debate going on in regards to reference
designators. We have (long ago) adopted IEEE 315 as the "bible" for
schematic symbol and reference designators, but the standard seems
misleading.

Take for instance OP-AMPs should have "AR" as the designations,
OSCILLATORS should be "G", ATTENUATORS should be "AT" according
to how you interpret the standard.

But, aren't these all, in fact, microcircuits ("U") or integrated-circuit
packages in today's practice? Does anyone else have a better system
for defining reference designators, per "some" standard? It seems IEEE-
315/315A should have been out-dated long ago.

Help?
