Working with Designs

A design can be opened for reading or editing. To open a design, you select Open from the File menu in the command interpreter window (CIW). A form is displayed for you to specify the library, cell, and view name of the design and the access mode, which can be edit or read.

• Edit mode excludes other users from editing the same file, although they can still view the old copy saved to the disk.
• Read mode allows users to share design files.

Whether a design is opened in edit or read mode, all designs under the hierarchy of that design are opened in read mode. The only exception is edit-in-place, where both the top design and the design being edited can be modified; the other designs maintain their non-modifiable status.

After a design is opened, you can change the mode from read to edit. If a design has already been modified, changing the mode from edit to read makes the system to prompt you to save or discard the changes made. If you choose the discard option, the changes are ignored and the original design is brought back from the disk. You cannot make a cell editable if you do not have write permission. The name of the current design and its mode are displayed in the window banner.

Working with your designs involves the following basic tasks:

• Opening a New Design
• Opening an Existing Cellview
• Making a Design Read Only or Editable
• Saving a Design
• Closing a Design
