Well I am currently developing an EDA app at this moment which you are
welcome to use. If all you need is schematic capture at this moment,
then it has all the capabilities you need. PCB Layout I am still
working on.

All the various symbols, contacts etc. that you need you can easily
define yourself in the symbol editor. Just build your own library of
symbols.

As I haven't needed it yet I have not yet implemented the ability to
actually print a schematic but this would be reasonably easy for me to
implement and if you wanna use it, I would prioritize it and get that
implemented asap. I figure that is something that would be rather
important for you =)

Note however that this app is in development so there will prolly be
the occasional bug and rough edge. I try to do all the testing I can
as best as possible but me being the programmer I am the worst person
to do any testing!! So I am looking for as many people as possible to
work with this and help me test it.

If you are interested, make a post here or send me an e-mail at

And to make PCB -> gerber:

And then there's KiCad:

It sounds like you're squawking about having to build your own symbol
library.
Get over it. Everybody who uses a CAD has to do it.

Yep! I trusted Orcad's symbol library once... exactly once! The white wires
were manifold.

They did silly things like assume the pin numbering was the same between the
7805, 78M05, 78L05, LM340-T5, ... Diodes with the anode sometimes #1, and the
cathode sometimes #1. LEDs with yet another numbering...

So hey let me ask ya. Is it even worth my effort to try to include a
standard set of symbol libraries?

I don't really have the resources to manually create my own libraries
for every existing component out there so I would need to create my
own libraries based on other existing ones.

PCBCAD17 off ebay is a great little program and only a few pounds.

See. Joining an EXISTING thread
instead of starting your own SPAM thread is just as easy.

Ignoring the contents of Subject line and advertising your payware,
however, puts you right back in the Stupid category.

Your TOP-POSTING flags you as clueless as well.

Imagine who your target audience will be.
Imagine that guy wanting to test-drive your ECAD.
At a miniumum, include enough
so that the experience will not turn him off immediately.

Lack of good libraries (as the OP notes)
could be a big turn-off for some folks.
(You expect to have to DIY on exotic stuff--however...)

Worth noting: EAGLE puts up Share-Your-Stuff pages for its users.

Have you investigated gEDA and KiCAD?
Is there something in their philosophies
that makes you want to start from zero
instead of contributing to a project with momentum?

The old original PSpice Schematics allows sending your schematic file
in a way that includes all the symbols you used (*.ma).

Something like that I could easily set up and would be happy to
support. Matter of fact, I would be happy to even support other
packages libraries as long as I can get the appropriate documentation
of their file formats to be able to at the very least import them.

gEDA and PCB use open and fully-documented library formats, so no
problem there.

Heck, you could just use the same formats and save yourself some
effort.

One question for ya, how much is "enough"? =)

Quote:

I agree with you, and that is one area I have a problem in. I can
handle writing the software, my current goal is a release towards the
end of the year. No problems there at all. Single-handedly writing
applications of this scale is something I do on a regular basis...this
is just the first time I am doing it for my own product.

The symbol libraries and pattern libraries do worry me though. I want
to provide good and accurate libraries but for me to create them by
hand is unfeasible. I have time, but I don't have that much time. I
mean something basic with some basic patterns and components, sure no
problem. But there is no way I could cover even all the standard
components, exotics included, of all the standard manufacturers.

So that essentially leaves me with the following options:

- Import options for libraries from other packages, that I plan to do
anyway. The more the merrier...I currently do support P-CAD ASCII and
definitely have interest in supporting more, documentation is hard to
find though.

- Using existing libraries from say another package, build my own
libraries in my format based on their data. At this point in time
though, I need to trust that their contents are valid and accurate. I
also don't know any potential legal implications in doing something
like that but on the other hand, the symbol definition for a given
chip is the same no matter whose library it is, same for the pattern.
So all the data being copied really isn't anything proprietary. And at
this point in time, that is the most feasible option to me.

- Create a global portal available to all users that initially just
contains a very basic library and give the users the ability to expand
it and/or add additional libraries. Anything added to this portal is
instantly available to all other users. So over time the libraries
will grow in content and accuracy. Users would still of course still
have the ability to have their own private libraries locally.

This however would not truly be feasible until I have enough cash-flow
to support the required server infrastructure for something like that
so it is more something to consider for future expansion rather than
the beginning.

See above =)

Nothing to do with their philosophies, I just simply don't work for
free. I have a car payment, rent to pay, etc. And I would much rather
make my living off my own product than being employed at some random
company working my butt off for some salary while the company gets
rich off my work. =) For those reasons I have no interest in
contributing to open source projects.

I figured they would so I will definitely be looking into those and
adding support for that.

Quote:

Well not really, one is due to potential legal implications. Secondly,
using someone elses format limits me to what their format is capable
of storing. If I ever implement features that require me to store data
their format cannot handle, I have a problem. Sure I can extend the
format but at this point in time, it is no longer the same and no
longer compatible with the other app.

Plus my format is already defined anyway and is working very nicely!
The format is also designed in such a way that it is usable for
symbols, schematics, patterns, and pcb's (just the stored data
elements change accordingly) to avoid needing multiple file formats
for the various different files.
