Cameo Simulation Toolkit allows you to control a model simulation using the debug buttons such as Suspend, Resume, Step into, and Step over. The table below explains the functions of all of the debug buttons.
| Button | Name | Shortcut key | Function |
|---|---|---|---|
 | Start Simulation | F8 | To start simulating an object of the initialized session shown in the Sessions pane. |
 | Restart | F8 | To restart the last simulated element. |
 | Suspend | F8 | To pause a running simulation session in the Sessions. |
 | Resume | F8 | To resume a simulation session. |
 | Step into | F5 | To simulate and animate a currently active element in a selected simulation session in the Sessions pane. |
 | Step over | F6 | To simulate a currently active element in a selected simulation session and run animation in the background. |
 | Terminate | None | To stop a session in the Sessions pane. If the selected session contains sub-sessions, all of the sub-sessions will also be terminated. |
You can examine and edit variables in the Variables pane (see Variables Pane), pause the a model simulation at predefined breakpoints (see Breakpoints), or simulate one element at a time using the Step into or Step over button.
The Debugger pane includes a player-like control panel for a step-by-step simulation (see the table above), threads or Behaviors with an expandable stack trace (see Understanding simulation sessions), input/output console for custom commands or expressions evaluation (see Simulation console), Variables pane/runtime structure (see Runtime Value Monitoring), and Breakpoints pane.
