Database Maintenance: DBDoctor

mahimag

The DBDoctor application checks the database for errors and other problems, and presents a report about them. DBDoctor supports .brd, .mcm, .mdd, .psm, .dra, .pad, .sav, and .scf databases.

DBDoctor can:

  • Analyze and fix database problems.
  • Eliminate duplicate vias.
  • Perform batch design rule checking (DRC).
  • Upgrade databases more than one revision old.

To verify the integrity of a drawing database at any time during the design cycle, run DBDoctor at regular intervals but make sure you always run it after completing a design.

You can run DBDoctor to verify work in progress, or from a terminal window outside the layout editor, perhaps to check multiple input designs in batch mode by using wildcards and various switches. You do not have to run the layout editor to use DBDoctor.

To run this from Allegro X APD and Allegro PCB Editor, go to Tools > Database Check.

  

You can also go to the Start menu and select Cadence PCB Utilities 2023 > PCB DB Doctor 2023.

  

You can also use the following command to run DBDoctor in batch mode in the system command prompt:

dbdoctor [-check_only] [-drc] [-drc_only] [-shapes][-no_backup] [-outfile <newboardname.brd>]>

 

Comment below if you want to know more about this command and its integration with SKILL programming!!

    I see a reference to running in batch mode. I have not been successful in working out the process. Do you have an example?

    I am doing a bunch of pads and footprints.

    Thanks!

    As input, wildcards are accepted. You can try entering *.pad, *.dra, etc at the utility will convert an entire directory and update files accordingly.

    I have launched PCB DB Doctor 24.1 (as a Windows app) and entered *.pad. It not did not work. I will check it again.

    Best regards,

    Fred

    Hello   if you give location of the pad files and then add *.pad at the end, it should work
