Re: gEDA-user: Heavy Symbols and such

["Steven Michalske" <smichalske@xxxxxxxxx>]

Having the schematic be a generic light symbol is a nice idea with
having a BOM/database translate the part.

I can see that having one symbol be a micro-controller, and having a
part choice stage.  either in a BOM or by an attribute added to the
schematic.

I currently use heavy symbols in gEDA because it is simple to have a
BOM generated from the schematics.

on the other hand,  if i had a robust database driven solution that
allowed me to use light symbols and choose parts as I placed or choose
in a separate UI for BOM management (gBOMer :-P ),

This way if i want to use a AT mega 8,  i have a list of variants; the
slow part, the fast parts, the parts that have different foot prints.

now from PCB lets say we get back annotation  through some form of IPC
if i get the info on a resistor i specified that in my schematic that
i wanted 1/10th watt 1% 330 Ohm resistor,  in PCB I could then choose
anything from the 0603 variant to the 1206, even a through hole
variant because it lets me cross 5 traces and simplify layout.


This way my engineering project managers could have a nice interface
to the design process,  get updates of new parts added, parts removed,
this would make our tools even more attractive to commercial users.


just some thoughts
