In majority of the cases, subscripts or superscripts are appended asIn data books, the draftsmen who create the symbols will show names like "VCC"
with the "CC" subscripted as you'd expect. Does anyone know of a schematic
capture tool that supports that use of sub- and super-scripts in pin names?
Thanks,

Sure, they "work" just fine, but it's too bad that CAD software doesn't makeIn majority of the cases, subscripts or superscripts are appended as
text next to V, so VDD or VCC would work just fine.
These days I never hide power pins... it's quite uncommon today to haveCare must be taken
in the cases where some chips have VCC and VDD as power connections
and they are hidden in the schematic.
It would be a pretty stupid engineer who didnt know what VCC was if it"Mak" <mansoor.nas...@gmail.com> wrote in message

it easy to have them *look* the way they were intended as well.

These days I never hide power pins... it's quite uncommon today to have
designs that don't have multiple rail voltages running around.

You're missing the point: Just because one can get by without subscripts,It would be a pretty stupid engineer who didnt know what VCC was if it
wasnt in superscript !
I use up to 8 character net names in my software and it works fine.
But you have to draw a line somewhere, you cant go on adding functions"Marra" <cresswellave...@talktalk.net> wrote in message

You're missing the point: Just because one can get by without subscripts,
lower case, (effectively) unlimited length pin names, etc. is no reason to not
support them in a piece of software. Heck, people got along just fine on PCs
when file names were restricted to upper-case only, 8.3 characters, no spaces,
etc... but I'd wager that most people wouldn't want to go back to that system,
now that they're used to being able to do more.
Sure you can. And keep in mind that, if the features are truly useful, if youBut you have to draw a line somewhere, you cant go on adding functions

Yes, version 1.0. Then you sell version 2.0, 3.0, 3.1, then 95, 2000, XP,At some point you have to sell the software.
I'd modify that to Einstein's "Everything should be made as simple asThats a bit like debugging. Keep it simple and you shouldnt get as
many bugs.
Agreed, this is a significant danger. Good companies often prioritizeGet into bloatware and you will never meet deadlines or in some cases
ever finish coz the plug has been pulled.

You forgot to mention the codebase fork. ;-)
