Using the Electric VLSI Design System

Chapter VIII: CREATING NEW ENVIRONMENTS

| ## 4: Miscellaneous Information |

### The Miscellaneous Information Facet

Each facet in a technology library describes a different aspect of the technology. The miscellaneous information facet contains technology-wide information. To see this, use the Edit Miscellaneous Info command of the Technology menu. Note that since this facet is called "factors", the same effect could be accomplished by selecting it with the Edit Facet... command of the Facets menu. The miscellaneous information facet contains two items: the value of lambda (the basic grid unit, measured in internal units), and a full description of the technology. By highlighting any of these items and using the technology edit button, the item can be appropriately modified.

### Additional Variables

Besides the information shown in this facet, there are many optional variables that may be specified with the Edit Variables... command of the Technology menu.

This dialog shows two lists of variables that can be attached to the technology. On the left is a list of variables that are currently attached, and on the right is a list of all known variables that can be attached to the technology. To add a new variable to the technology, select it from the list on the right and click the "<< Copy" button. To remove a variable from the technology, select it in the current list and click the "Remove" button. When a variable in either list is selected, its description and type are shown. When the variable is of type "Integer", "Real", or "String", you may change its value in the "Value" field. When you have selected a variable of type "Strings" (note the "s") then it must be edited in a separate window with the "Edit Strings" button. The "Edit Strings" button first exits this dialog and then opens a text edit window for manipulating the variable. See section 4-10 for more on text editing.
