Virtuoso

• Layout tutorial from Berkeley
• To add labels and pin names etc., they have to be attached to a geometry, which means a wire net. To add a label such as “INV M12” where “M12” is a specific transistor in the schematic, using the “add label” button on the left, Select The Text Layer first, then open the label window, check the “Attach” checkbox, and after the label is placed, you have a connector attached to the mouse from the label which needs to be placed on a wire or it won’t pass DRC. Adding this kind of label probably also names the wire net, so I'm sure that there will be problems later if

-At the shell prompt, type clsAdminTool, you'll get a > prompt.

-Type ale /afs/asu.edu/users/m/b/a/mbaker7/cadence/EE525 (using the correct path to your library). You should get a list of existing locks in that library.

-There are two ways to release the lock in question:

To release all the locks in the library, type are /full/path/to/your/library/directory

To release the lock on a particular file, type asre /full/path/to/the/locked/file

-Type quit or exit.
