In physical mode, the user has wide freedom to apply properties to cells, subcells, and objects. The only constraint is that the following number ranges are restricted and must be avoided, for arbitrary user-specified properties. However, there are some properties within the range that can be set by the user, that have specific syntax requirements and meaning to Xic. These will be described.
The property number ranges used by Xic are:
The Property Editor from the Properties button in the Edit Menu is used to assign properties to cell instances and objects within the current cell. The Add button in the editor allows addition of special properties used by Xic, and arbitrary user-specified properties. See the Property Editor description in 10.10) for a description of the properties that can be added.
The object's existing properties, and available pseudo-properties are listed in the Property Editor, with color and syntax coding to indicate the classification. Pseudo-properties are not actual properties, but when applied to an object will change or report some parameter of the object.
The Cell Property Editor from the Cell Properties button in the Edit Menu allows editing of the properties of the current cell. See the Cell Property Editor description for a list and discussion of the cell properties that can be added with the Add menu.
A description of the physical properties used by Xic, including the property string syntax, is provided in D.1.
