L-Edit version 16 and up introduces several UI changes from previous versions of L-Edit. CNF IT has worked with Tanner support to document and work around these changes as best as possible.
No longer a standalone UI panel, the list of layers is now combined with the list of cells in the open design file. This UI panel contains two tabs: Libraries and Layer Palette. For new design files, the default is to display the list of cells and not the list of layers. To see the usual list of layers, click the Layer Palette tab.
L-Edit 16 and up supports a second database file type called OpenAccess. As a result, L-Edit 16 does not automatically read in the CNF defaults file (ledit.tdb) and does not start with a new cell in a new design file, ready for the user to begin drawing. To work around this problem, one can first open the CNF ledit.tdb file. See below for more information.
c:\Program Files\MentorGraphics\cnf
/usr/local/cnf/ledit
On linux, in the file dialogue you can type in windows equivalent drive letters 'W:' and 'V:' to access your home folder or the lab transfer share.
DO NOT attempt to browse into the top level "/afs" folder. This will lock up L-Edit.
On the CNF conversion computers, Korat and Minx, type in: ledit .
On Minx only, the L-Edit command now points directly to the CNF defaults file, ledit.tdb.
On Windows and on Korat, use File - Open to ledit.tdb from the CNF Files Location mentioned above.
This file is a system file and cannot be updated by users. So, upon starting L-Edit, users will receive the following error message:
File "...ledit.tdb" can be opened only for reading. Changes to it cannot be saved.
Do you want to open it as Read-Only?
Answer Yes. If users answer "No", L-Edit will not load the CNF default settings and will not start with a new Cell in which to draw.
When saving the design file for the first time, users will choose Save As from the File menu. In the Save dialog box, users will then need to browse to a location to save the ledit TDB file. In the Linux version of L-Edit, this will be My Computer - W: and then some subfolder of the AFS home folder.
The best way to start a brand new L-Edit design file is to close and re-open L-Edit. Closing and re-opening L-Edit will reload the CNF defaults and start the user with a fresh cell in which to draw.
With the help of Tanner technical support, CNF IT has installed a macro file to assist with the steps of creating a new TDB design file with the CNF defaults from ledit.tdb.
Unlike when freshly starting L-Edit, users will not get a new cell in which to draw (this would appear to be a bug in L-Edit). Users can instantiate a new cell by either:
In both cases, the cell name will default to Cell1 and not Cell0. But, users can simply choose to name the new cell Cell0 if so desired.

CNF Libraries are located in /usr/local/cnf/ledit (Korat) .
Unlike the Windows v15 version of LEdit, the window for instantiating a new cell does not allow you to select a library file. The dropdown only allows selection of existing libraries.
