Exporting library from old design files

stantheman286

Hi everyone,

I've been searching on this forum and others, and so far haven't found an exact answer to my issue and I'd really appreciate your input.  I'm coming back to OrCAD after a few years with other tools, and even then I was a relative newbie, so my knowledge in this area is fairly limited.

What I want to do is take our previous design files (.dsn and .brd) and dump the parts data into a library (.olb) and symbols files (.dra, .psm, etc).  Ideally, I'd like to upload these parts into our CIS database to use with data downloaded from CIP, but for now a local library is my first goal.

I have exported an .olb from my old .dsn file by copying the design cache to a new library and saving it.  I then exported the part symbols from the .brd file using Export > Libraries.  I updated psmpath and padpath to point to the symbols directories I exported the part data.  I also updated my capture.ini for both the library and symbol locations:

[Allegro Footprints]
Dir0=C:\git\new_design\Symbols\Board1
Dir1=C:\git\new_design\Symbols\Board2
Dir2=C:\Cadence\SPB_16.6\share\pcb\pcb_lib\symbols
Dir3=C:\EMA\CIP-E\Allegro_Library\symbols

[Part Library Directories]

Dir0=C:\git\new_design\Libraries
Dir1=C:\EMA\CIP-E\Schematic_Symbols

When a create a new design and add the new library I've created, I'm noticing that when try Show Footprint on a number of the parts I've placed from the new library, that I get the "Allegro footprint <PART> was not found in the search path" error message.  However, in the old design file, if I place parts from the design cache (not my new library), the part previews show up when I click Show Footprint.

The old design files were copied from our previous designer's machine, and therefore the paths in the design cache and symbols information are incorrect, which I thought might be the issue.  Do I need to run a Replace Cache on the old .dsn and point it to my new library before exporting again?  Do I need to run a Place > Update Symbols before exporting from the old .brd file?

Thanks!

Matt

    Ah, yes thanks for explaining that.  I was able to go in and modify all my symbols that were pointing to the wrong footprint.  It looks like everything is resolved now, I'm getting the footprints when I view them in Capture and they're placing correctly in PCB Editor.

    Thanks!
