Assigning different library to device in schematic using ULP

Hi,

I'm new to Eagle(v7.7) and new to these forums as well. I've searched for an answer to my question but have not had much luck so here I am.

 

Our current process, during development, is to use an unverified library for any new components, and a verified library for components already in use in our other products (we've used them, the footprints are correct, the part numbers are correct, etc etc).  Part of the release process is to review those new components and move them into the verified library. To avoid duplication and errors, the version in the unverified library gets deleted at this time. This is all well and good, except the component on the schematic will still reference the unverified library, where the device no longer exists. Manually replacing each component on the schematic with one from the verified library would work, but it doesn't sound like a whole lot of fun. My thought was to write a ULP to handle this. I can successfully identify every device using the unverified library using :

 

schematic(S)

{

     S.parts(P)

     {

          if(P.device.library == "Unverified")     <<~~~~~ Unverified is the actual name of the library in this example...   Unverified.lbr

 

 

I tested this and it successfully identified every component referencing that library. My logical next step (that is apparently not so logical) was to simply assign the new library name after the if statement. So I did this:

schematic(S)

{

     S.parts(P)

     {

          if(P.device.library == "Unverified")

          {

               P.device.library = "Verified";

          }

     }

}

 

Unfortunately, I get a syntax error on the line P.device.library = "Verified";        but I don't know why. Any help would be greatly appreciated.

The limitation is that you can not modify any data from within a ULP.

The concept is to use a ULP to extract or analyze data, then produce a

script file (.scr) to effect any change to the data.  In this manner,

one should collect all the script commands to be executed in a string,

where each command ends with a semicolon, and is separated from the next

command with a newline.

string cmds;

    string cmds;

    cmds = "group all;\n";

    cmds += "smash (C>0 0);\n";

    cmds += "group all;\n";

    cmds += "change font vector (C>0 0);\n";

Once all the the commands are collected, they can be executed upon exit

from the ULP:

    exit(cmds);

Unfortunately, I do not believe one can change the source of a library. 

A three-step approach may be needed, and it can all be done from within

a single ULP.

1. Identify all the devices that need to be copied from the unverified

    to the verified library, and place these device names in an array.

2. Open the Verified library:

    cmds += "open Verified.lbr;\n";

3. For each device in the array: Copy the device from the unverified

    library:

    for ... {

        cmds += "copy mydevice.dev@Unverified.lbr;\n";

    }

4. Open the unverified library

    cmds += "open Unverified.lbr;\n";

5. Delete the devices that were copied:

    for ... {

        cmds += "remove mydevice.dev;\n";

    }

6. Execute the commands:

    exit(cmds);

As for updating the schematic, for each of the parts that were moved to

Verified.lbr, you'll need to do a "replace (click coords)

device@Verified.lbr;\n".

That's a rough outline.  I've never had occasion to open different

windows and execute script commands from within a single script, but it

might work.  If that doesn't work, you'll have to split the script up

into multiple segments.  In the first script, you'll have to emit the

devices of interest to a text file, then in subsequent scripts, load

them into an array.

I know this is not complete, but it should provide some ideas on how to

automate this process, at least partially if not completely.

Hi Bob

Give the attached ULP a try.(zipped)

It assumes that all unverified parts used on the schematic are now in the verified folder.

Assuming "unverified" and "verified"are not the real names, you get to select from the list of library names used in the schematic. Then you choose the destination library name. If its not already in use in the schematic you can "Browse" for it .

When displayed along side the browse button, that library will be the new name used . If you want to change your mind at this point, click in the right hand 'target' list and the browsed for selection will be cleared and you will be using the one selected in the right hand list.

Enjoy

Thanks Warren! I was hoping for a point in the right direction....a working ulp is even better! I'll give it a shot asap.

Just a follow-up... I tested the ULP and it works perfectly for what I wanted to do. Thanks again!
