Abrupt closing of Allegro PCB Designer software

Rahul24

Hello everyone,

I am using Cadence Allegro PCB Designer 17.2 for designing a PCB board. The software worked well for many days as I progressed till the last part of my design.
Recently, when I was finishing up things, I ran a DRC check through the path "Display > Status > Update DRC". The software ran a multithreaded DRC and closed abruptly. No changes were saved in the file after my previous saved session.

Secondly, when I tried adding "aperture" files using "Artwork Control Form" window, the following error appeared. However the board file gets saved, all the Allegro software windows close abruptly.

"The program has encountered a problem and must exist. The design will be saved as a .SAV file that can be recovered by using a dbdoctor (if applicable). To resolve problem, first obtain the latest software update from Cadence and if the problem persists contact Cadence Customer Support. In addition to the data Cadence support requests: please provide the MiniDump files found in the folder: "C/Cadence/.... ".

 

The artwork window is not allowing me to add aperture files. Just to add more info, I had designed the board in "mm" and to create artwork files, I had to change the units from "inch" to "mm", which gave me a warning of loss of accuracy, which is not a matter of concern for my design. I wonder if this mismatch is the cause of above errors.

I would like to mention that these problems are occurring for only this particular board file.

The software is working absolutely fine for other board files, is able to update DRC and create artwork files.

It would be great if someone could help, suggest about what exactly is going wrong in the board file and how these issues can be rectified.

Thank you !

Regards,

Rahul

    Try a Tools - Database Check, check all the options and click on Check, then once finished click on Viewlog to see if there are any errors in the database that were fixed. (The tools normally remind you to do this when you change units. Also make sure you are running the latest hotfix (currently S012) whch you can check from Help - About. If yoy are running P004 then that's the base release and you'll need to login to Cadence Support to access the latest version.

    I tried the option Tools-> Database Check option. There were some errors in the board which were fixed by the software. After this step, I could update the DRC and everything worked smoothly. No issues with software or license as such.
    Thank you so much for the help Steve!

    I have found the software to crash frequently upon Autosave.
