The Edit Button: Edit Cells
The Edit button is used to read a file and load a cell for
editing. The button presents a drop-down menu containing the names of
the last eight cells opened for editing, plus a ``new'' entry.
Select new to open a new cell by giving a name on the prompt
line. The default name of the cell to edit will be one of the
following. Each of these sources is tested in order, and the first
one that is visible and has a selection will yield the default cell
name.
- A selection in the File Selection pop-up from the Open
button in the File Menu.
- A selection in the Cells Listing pop-up from the Cells List button in the File Menu.
- A selection in the Files Listing pop-up from the Files
List button in the File Menu, or its Content List.
- A selection in the Content List of the
Libraries pop-up from the Libraries List button
in the File Menu.
- A selection in the Cell Hierarchy pop-up from the Show Tree button in the File Menu or from the Tree
button in the Cells Listing pop-up.
- A cell name that is selected in the Info pop-up, from
the Info button in either the View Menu or the Cells Listing pop-up.
- The name of a selected subcell in the drawing window, the most
recently selected if there is more than one.
- The next cell from the command line invoking Xic.
- The current cell name.
If one holds down Shift while selecting one of cells from the
history list, the Cell Placement Control panel will appear with
that cell added as the current master. This applies to cell names and
not new. This is a quick backdoor for instantiating cells
recently edited.
The Edit button also allows text editing of two special files.
If the name of the file given is that of the present model library
(default ``model.lib'') or device library (default ``device.lib''), the library file is first copied into the current
directory if it doesn't exist, and the file in the current directory
is then opened for text editing. These files contain the devices and
some of the models used in electrical mode for producing SPICE files.
If a cell is opened for editing that contains empty symbols, the user
is given the option of deleting these references. This test can be
suppressed by setting the NoCheckEmpties variable. If empty
symbols are found in the hierarchy, a pop-up appears, which allows the
user to delete the empty symbols. This test can be performed at any
time with the !empties command.
