Session

When you invoke Sonnet software, you start a session. A Sonnet session defines what Sonnet software is presently running, including what modules (tabs) are open, and how the interface tabs are configured. You may only have one session running at a time but there is no limit to how many windows and tabs are created, nor how many projects are opened. The session manager which appears in every type of Sonnet tab, including the default session tab, allows you to keep track of every tab and project that is open in the present session.

It is important to understand the distinction between a session and a project. Double-clicking on a project opens a Sonnet session with that project open in an Edit tab, but the project does not store information about the session. The session information is automatically saved and used the next time you open a session. You can also manually save and load sessions if you wish. It is also possible to reset your session to the default state.

By default, when you open Sonnet, your previous session is automatically loaded. If you wish, you can also save a session in a session file (.sesn) for later use. A session file stores the following information:

•     What tabs are open.
•     What projects are open and in which tabs.
•     The window configurations of the tabs including placement of panels and toolbars.
•     Contents of session manager.

A project can be opened and used in a session. The follow information is stored in a project file (.son):

•     The geometry layout (Geometry project)
•     The netlist (Netlist project)
•     The stackup information
•     Materials information
•     Variables
•     Preferences
•     Analysis sweeps
•     Analysis data

While it is possible to save a session, a session may not be packed. If you wish to send a graph to another user, you should save your plot in a graph file (.sgrx) by selecting the File - Save command in a Graph tab, then send the packed projects and graph file.
