My enviornment uses the clio DM system. When I go to create a new library, Cadence asks for the cds.lib to checkout. A lot of times the managed file is locked and I cannot edit it. For this reason I create a non-managed "cds_custom.lib" that I include in my "cds.lib". If I specify a filename that is not "cds.lib" in the"Check out cds.lib" form that comes up, it fails to edit anything and I cannot create a library.
Is this a DM bug or Cadence bug?
If it is a Cadence bug, it seems trivial enough to change to allow any file name to be modified, as in my example a user may need to modify a referenced library file in the same path as the cds.lib.
Because that's the way it is and has been for the last 16 years or so... there's never been enough demand to change it (as far as I know). By all means contact customer support and request that though...
