Often if there is a problem shutting down any of the Cadence products, lock files may not be removed properly. This leads to warnings in the program or the inability to edit your projects. Execute the following to clear or identify your Cadence lock files :


  1. Log into one of the Linux Compute servers. https://www.engr.colostate.edu/ets/linux-compute-servers/ and open a terminal window.
  2. Load the Cadence/Virtuoso Module
    • module load virtuoso
  3. Start the Cadence Admin Interface
    • clsAdminTool
  4. Type "help" and hit enter for all options, or choose from one below. The directory we will be using is ".", shorthand for the current directory you are in. Feel free to substitute for your directory of choice, but be aware that Cadence products produce lock files in the top level of your home directory, even when starting the program elsewhere.
    • To list all lockfiles
      • ale .
    • To remove all lockfiles
      • are .
  5. Once you are done, type "quit" and hit enter or close out of the terminal window.
