Wire list from board

Hi,

    I wrote a "WIRELIST.ulp" and submitted it to the Eagle ULP library (see

near the end of the ulp list).

It does exactly what you need, and a bit more.

    I needed a BRD file,  "post processor",  after an Eagle board is

populated, to create an "optimized wire length point to point wire wrap

list" - so I could test a project using a prototype project board, before

committing to a PCB.

The wire lengths are scanned and optimized. The resulting TXT file contains

NET names (based on the signal name), the name of the component, the pad/pin

number and its XY board coordinate, and point to point length of wire.

    You can even graphically display the wrapped wire runs on the BRD, just

like a routed PCB air wire display.

The TXT file header will also contain the "date and time of the run", just

to keep track of and distinguish parts placement changes, that occur during

iterations of the project during development.

    There is an extensive description and user guide in the ULP comments

header.

Since I wrote it in an intensive session over two years ago, for Eagle rev

4.15, I really don't recall all the details, but it is fully debugged, and

fully documented.

Hope this helps.

Joe

    Here is a "sample output" section  (ALTAZ-JAZ-24C.txt),  of one of my

normal Eagle  BRD projects:

If one would wire the project in this exact sequence, it would use the least

amount of wire, and therefore shortest point-to-point signal run.

Hello,

 

I have a board layout, and want to create a ASCII file that lists all the

net names and components that make up each net.

 

I have tried to Export a Netlist from the board, but only get the

following:

Thanks for the suggestion.

I downloaded the UPL and ran on the board and got the following output:

Same results as running the EXPORT NETLIST.  I think what has happened here

is that the board was created without a schematic.  Parts were simply placed

schematic, then create a new board with the necessary revisions.

Thanks for your help.

Hi Greg,

    I just scanned through my postings to the  "Eagle.ANNOUNCE.eng" group

about my WIRELIST.ulp.

I forgot to mention that I later added a ROW and COLUMN number beside the XY

(mm) coordinate, so you could wrap (or solder) socket pins by simple number

pair.

   The output is NOT a TXT file, but an SCR file - which can be renamed to

TXT, for printing, or executed directly by Eagle as an SCR command file.

Essentially, the SCR is a list of SIGNAL command lines, with text and

comments that won't bother EAGLE during execution. Each SIGNAL subsection is

terminated with a single "comma" to tell Eagle it is the end of that NET

signal.

(I had to double check this, since it has been so very long, since I wrote

it).

The best thing is that the resulting SCR executed on a BRD with parts but

no air wires, gives a perfect way to verify a person's wiring job, by using

SHOW to high light the wire path for check out purposes. The only problem is

that Eagle does NOT have a VIEW-->Mirrored option in the menu,so we wouldn't

have to flip the wire wrap project board, mentally, for verification. I have

posted this suggestion yesterday, as well.

Here is a more accurate description of the output format:

You can read the complete original posting of my upload, in a

"Eagle.ANNOUNCE.Eng" group email

dated September 19, 2005 12:35 PM   -  WIRELIST.ulp: Creates a project

board Wire Wrapping run list & SCR file

Cheers,

Joe

********************************

OUTPUT:

    A formatted document  "<BRD-name>_WW.SCR", somewhat similar to that from

Richard Hammerl's TESTPNTS.ulp, from which this project started.

The headings start with (#) comment lines, to be compatible for execution,

directly, unedited, as an SCR script.

Columns include:

***

(a) NET name,

(b) PART name,

(c) Pad number, (ending in (#) for SCR compatibility)

(d) PIN-X and PIN-Y board wrapping post position, (suspect positions are

flagged with asterisks )

(e) X and Y board pad coordinates in mils,

(f) WIRE LENGTH in mils, of segment

(g) COMMA - mandatory, on a separate line, after each final signal segment,

to

close that NET's, SIGNAL COMMAND line string

***

USE:

    Produce an Eagle board, and layout out all the parts. This can be done

from scratch, or from Eagle Schematic Editor.

If the board is created directly, using only Eagle Board Editor, then

manually

route all the parts pads first, to produce NET signals.

Run WIRELIST.ULP "in the board". You may then use Eagle Editor, or any text

editing program to view, or print the

wire wrapping file "<BRD-name>_WW.SCR" for board production

Same results as running the EXPORT NETLIST.  I think what has happened here

is that the board was created without a schematic.  Parts were simply placed

and connected with traces.... without a ratsnest.  The board is not too

complicated, so I should be able to trace the board out and then create a

schematic, then create a new board with the necessary revisions.

Ah, that is your problem.  A netlist is a list of signals that connect pins

together.  If you don't have any signals than your netlist is going to be

empty.

A wire is just a piece of copper and should never be used for routing

traces.  There are lots of postings about this.

When routing you should use a "net" and this becomes the physical

implementation of a conceptual connection (ie. A signal).  With no signals

there is no netlist.

When you lay down copper the way you did (with a wire) there is no internal

connection between the copper and the pin.  It overlaps so it will have an

electrical connection in reality.  But there is no signal involved here.

You would have to write a special ULP that would look for copper that

overlaps pads and smd's.  It might exist but I haven't seen one (although I

haven't looked either).

I hope this helps.  If you want a netlist then you could go back and use the

signal command to create signals for each wire you've put down.  The

ratsnest may not be able to resolve it but you'll get a netlist.

James.

Hi Greg,

    Thanks for bringing that to my attention.

I assumed you had gone through a full creation of the BRD, from an SCH.

   Still,  I wonder if creating a board directly, naming signals, and

running a ratsnest, might still create a normal Eagle netlist file, ( which

would still make the wirelist ulp work).

Then again, perhaps the standard Eagle Netlist is all you need, if that

would happen.

Check what production files Eagle created for you, when creating just a BRD

file (with your named signals).

Good luck,

Joe
