Working Copies
When you open an application, OpenROAD Workbench creates working copies of its components for you to modify using the appropriate editors. The working copy of a component can be one of the following:
Current version
Specifies a component that has been saved to the database and is available to all developers
Private version
Specifies a component that only you can work with
The OpenROAD version control feature lets any number of developers work on an application simultaneously. However, only one developer at a time can modify an individual component.
Each time you open a component to edit it, Workbench checks the component out of the database under your user name and locks it so that other developers cannot change it. Correspondingly, if the component is currently being edited by another developer, you can only view the component as it was before the current user began editing it. After the current user saves the component and closes the editor, then you may see the changes and make your own edits.
