Whats the deal with the BRD and SCH file format specification?

Are they described anywhere?

 

I am working on a content manatgement system for a client of mine, and

they would like to be able to view, but not edit, BRD and SCH files right

inside the content management system. The machines running the CMS will

not have Eagle installed on them.

How about printing them to PDF and viewing that?

Well, we can't do that with just the .BRD and .SCH files, and no copy of

Eagle installed!

Nice idea though.

Is the file specification publicly available, or even available via NDA ?

I think that's what is called "proprietary information". You'll hardly

get any internals/details.

EAGLE has very powerful export capabilities by use of ULPs, you can

generate about any format you desire. This is all you can get.

I understand that this doesn't help you much in this case, since you

need EAGLE installed for running the ULPs. Maybe it's a solution to

install the freeware on one of the CMS machines and automatically run

the needed ULP(s) on that to generate the data for your CMS?

Also the Eagle demo license allow all cam and ulp's to run. It just

restricts moving parts outside of the limit area.

Paul R.

our CMS here uses pdf's as the master documents, but each version record

can also attach native CAD ( ie .brd, .sch) files so one can work from

an old version if necessary. it seems to be a good system.

i expect attaching gerbers would also be useful if they are what you

send to your manufacturer. then nobody needs to read the EAGLE files

unless they want to fork the development of the board for some reason or

copy an old layout, etc.

That's exactly what I meant.

We are talking at cross-purposes - the person producing the brd/sch files

with Eagle also produces the PDF for each when they place them in the CMS -

Eagle V5 has a PDF "printer" built into File->Print... for free.

So, the CMS contains the SCH-PDF, BRD-PDF, SCH & BRD, but only the PDfs are

viewable as pretty much any CMS can view PDFs... The trick is to ensure that

the PDFs always reflect the latest BRD/SCH - In a previous life we used to

do this by using command line options from a scheduled job every night to

execute the print command - if you print to a file with a PDF extension,

Eagle will generate the PDF for you.... Have a look at the online help...

Cheers

FWIW: I have never - never - managed to read any Eagle exported data

into any other application. In particular I've been trying real hard with

netlists, but no application can read Eagle's output, and I have never

managed Eagle  to read any data exported by other applications.

So I'd gently resent "powerful export capabilities", because that

statement is anything but true.

The netlist (and other "direct" exports) use plain ASCII files, human

readable. I would never expect any other software to be able to import

these directly.

By use of ULPs you can generate any format and any content you desire.

If you need a format that is not yet available: write your own ULP. By

using ULPs, you have full access to the /complete/ design information.

So I'd gently resent "powerful export capabilities", because that

statement is anything but true.

I assume you didn't think of ULPs when you wrote that. Perhaps you are

not used to them.

Hello Rikard,

The default netlist export of EAGLE isn't any particular standard.  It's

easy to read if you are trying to do hand verification.  But I don't think

CadSoft ever intended it for inter-tool communication.

My company has a PADS netlist import/export tool.  I've personally used it

with success in both directions.  You can export a PADS netlist from an

EAGLE schematic and import into a PCB layout tool.  Or you can create your

schematic in another CAD tool and import the PADS netlist you get from it

to use EAGLE as the board editor.

Cheers,

James.
