New user using old symbols

GMPCB

Hi,

I am using Allegro 16.2 and trying to use parts made a few years ago with Allegro 14.7.

I try to open the .dra part and Allegro tells me that the database is too old, must run DBDoctor.

Fine.

I run DBDoctor on the whole directory of symbols and the logfile says that all symbols in that directory, 0 warnings, 0 errors detected 0 errors fixed.

I still cannot use the part or open the symbol .dra file.

Any ideas on how to keep my job? I could make new symbolss, but I cannot even see what was in the old ones.

Thanks.

    Try “uprev” in a DOS window

    uprev symname.dra

    uprev symname.psm

    Or

    For %sym in (*.dra) do uprev %t

    For %sym in (*.psm) do uprev %t

    To change all in a directory

    It is probably that you haven't upreved all of the elements of the symbol e.g. the padstack(s) that allows you to open it.
    I would suggets the use of the uprev or uprev_overwrite batch commands.There is a text document in

    <install_dir>\share\pcb\batchhelp\uprev.txt

    or you can type in a shell window

    uprev -help

    to get the usage.

    You may also want to look at Cadence Online Support Solution 11196164 titled "How to automatically update an entire group of files (.dra .pad etc) in a library directory at once" that describes how to create a batch file to update all elements of the symbol.

    Well, I hadn't thought of that... updating the padstacks.

     I included the padstacks and as much as I could find and tried it again. Here's a logfile of one padstack, seems a little vague.

    Performing UPREV on the database - G:/STE/PCAprojs/PCA-0070/Symbols/78c60d.pad
       Performing dbfix13 to bring DB up to REV13
       Performing dbdoctor14 to bring DB up to REV14
       Performing dbdoctor15 to bring DB up to REV15
    ERROR: Uprev failed!

    Which I found a little peculiar, so I looked at a logflile of one of the parts symbols...

    Performing UPREV on the database - G:/STE/PCAprojs/PCA-0070/Symbols/cap250.dra
       Performing dbdoctor14 to bring DB up to REV14
       Performing dbdoctor15 to bring DB up to REV15
    ERROR: Uprev failed!

     Any help would be appreciated. My schedule is getting a bit tight.

    Also, going more than one major software revision (14.x to 16.x) can sometimes be a problem.  If you have access to 15.x, open the symbol and save it.  Then you should be able to open it in 16.x and save it.

  • GMPCB

    I don't have access to Version 15.

    What I find interesting is that the symbols I am using were taken from another design, and I can look open the board file and see the components, but I can't open the components themselves, nor can I update them.
