Database Corruption Error in ADS 2014

ADS has been really frustrating me up by continuously giving this error when I try to open my designs:

(debootcb.ael line 2121, column 18)
Error opening library "Design_CDRX_PCBs_lib", cell "Detector_PCB_H_Ch", view "layout".
Corrupted database encountered: design Design_CDRX_PCBs_lib/Detector_PCB_H_Ch/layout

It does NOT happen during the same run (or even on the same day). Rather it happens after 2-3 runs. Also, it is NOT specific to Layout views only. It even happens to Schematic and Symbol views.

Can someone please give a way to avert this error once and for all?

Regards

Hi Ali_cmi,

I was also sceptical when ADS changed to the new database concept expecting this kind of errors.
But even with some crashes I have never seen a corupted database so far.
In several cases the lock on a design was not removed, but this is not really an issue.

Have you checked your system on stability ?
- Harddisk (checkdisk, Smart data), Main memory (Memory test), CPU (Prime95)?

I guess you have checked the (debootcb.ael line 2121, column 18) already and this does not show anything interesting ?

  Hello RUCKB,
  
  Thank you for taking the time to respond.
  
  I am NOT good in messing around in ADS errors that relate to anything other than simulation issues. Pardon my lack of knowledge, how to check what is in debootcb.ael? Where is this file located?
  
  My lock file issues turned to corrupted databases a while back. Now I am just resorting to backup in a new library. And yes, my drive is clean. Chckdsk reports it clean.
  
  Hope to hear from you soon.
  
  Regards,
  Ali

  Hello Ali,
  
  It's not really messing around, just debugging. There are often files reported that are related to any issue (also for simulation issues) and it can help to take a closer look to these files.
  
  .ael files are usually normal ASCII files and can be checked with any texteditor.
  I also do not know this specific file and the content, but if such a file is mentioned in an error message I first check my workspace directory for it.
  I just did a short check on this file, but there is no such file on my system (used "search everything" tool to check my complete system, not only workspaces, but also ADS installation directories).
  Seems this is spefic to your simulation ..

    I can't find the specific file but a file with similar name but different extension (.atf as compared to .ael) came across as I was looking. No interesting thing in it though.
    
    Just curious though, how can some files be specific to simulation? I am running plain S-Parameter simulations. Nothing too fancy though.

      I opened to deboot.atf file located here (C:\Agilent\ADS2014_01\de\ael\debootcb.atf) and its first line has something interesting to locate deboot.ael. Might help you locate the file. Here is what makes sense other than all the gibberish in it: cmake\projects\pde\ael\debootcb.ael
      
      Now I can't find this path. Kindly take a look at it.

      yes, I just searched for the .ael ..
      
      the .atf is the compiled binary version .. so nothing where we can take a look at :-(
      This is not simulation specific, but standard in the ADS installation directory.
      
      Guess I can not help you futher on this corruption as I have never seen this on my own ..
      As mentioned: do a complete check of your file system and your hardware and maybe also a fresh installation of ADS and copy your workspace to another place (e. g. different Harddisk).
      
      if it still happens I guess you need to contact your local FAE...
