Speeding Up Simulation

To simulate your model more quickly, disable options as described in the steps that follow:

1. In the Stateflow Editor, select Tools > Open Simulation Target.

   The Simulation Target pane appears in the Configuration Parameters dialog box.

   

2. Clear any of these options:

   • Enable debugging/animation — Clear this check box to disable chart animation and debugging.

     This option enables automatically when you use the Stateflow Debugger to start a model simulation. You can also control chart animation separately in the Debugger. (The Stateflow Debugger works only with simulation targets. Therefore, you cannot generate debugging/animation code for embeddable targets, even if you enable this option.)

   • Enable overflow detection (with debugging) — Clear this check box to disable overflow detection of Stateflow data in the generated code. Overflow occurs for data when a value is assigned to it that exceeds the numeric capacity of its type.

     Note   The Enable overflow detection (with debugging) option is important for fixed-point data. For more information, see Overflow Detection for Fixed-Point Types. To detect overflow in data during simulation, you must also select the Data Range check box in the Debugger window. See Debugging Data Range Violations in a Chart for more details.

   • Echo expressions without semicolons — Clear this check box to disable run-time output in the MATLAB Command Window, such as actions that do not terminate with a semicolon.

3. Click OK.
