Xic Variables

Xic maintains an internal list of keyword/value associations. Although this list can be used for general purposes, there are a number of special keywords, or ``variables'', whose value will affect Xic operation. Variables are set with the !set command, and can be unset with the !unset command. The script functions Set, Unset, SetExpand, and Get also provide an interface to this database. Variables can be set from the technology file, and a number of the buttons in menus and various pop-ups really do nothing more than control the state of one of these variables.

Any variable name can be set with the !set command. The variables and constructs that have meaning to Xic are summarized in the table below. These are described more fully in the sections that follow.
