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.

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.
