Electronic drawing standards question

D

Dave Boland

Guest
I've been looking at a lot of schematics over the last week
and it looks like there is no agreed set of symbols that
would constitute a standard. Or, some companies just choose
to do things their way. So I was wondering if there is a
stet of standards for symbols (and other aspects of
electronic drafting) and how I can get a copy?

Thanks,
Dave

That's the great thing about standards:

So many from which to choose.

AKA "The logical solution" IMO.

Another solution: Adopt one you think has esteem.

They are a classic example of a solution searching in vain for
a problem.

The great committee solution, almost as useful as the EDIF "standard"
;-)

Except that EDIF could have been great if the committee had been
competent. As it is, there are so many variations, that all follow the
standard, that the interoperability they envisioned is all but impossible.

My observation is that CAD companies try to make it all but impossible
to transfer data between different tools.

Did I just hear somebody make an argument for open-source EDA?

I like the competition (and cross-pollination?) that is beginning:

The *porting* thing is pretty cool too:

Are we talking about the same thing? IEEE 315 (-1975, and the 315A-1986
supplement) is the one with all the basic symbols; resistors (rectangle and
zigzag are both allowed), capacitors, inductors, BJTs, FETs, vacuum tubes,
etc.

In my experience most drawings follow this, but many get the details wrong
for less common components such as thermal fuses, transducers, ganged
switches, etc. It is handy to be able to look up the correct symbol for
things one does not use often.

IEEE 315 also has a list of preferred reference designators, which is a
handy thing to standardise on to maintain consistency between BOMs,
purchasing systems and CAD systems.

On the other hand "IEEE Graphic Symbols for Logic Functions" is more
controversial, and less widely used.

The Logic Functions "standard" was what I was thinking of... really
gross... totally non-intuitive!
