Using Simulink

Simulation Options Dialog Box

The Simulation Options dialog box allows you to specify simulation options pertaining to the Signal Builder. To display the dialog box, select Simulation Options from the Signal Builder's File menu. The dialog box appears.

The dialog box allows you to specify the following options.

Signal values after final time

The setting of this control determines the output of the Signal Builder block if a simulation runs longer than the period defined by the block. The options are

• Hold final value

• Selecting this option causes the Signal Builder block to output the last defined value of each signal in the currently active group for the remainder of the simulation.

  

• Extrapolate

• Selecting this option causes the Signal Builder block to output values extrapolated from the last defined value of each signal in the currently active group for the remainder of the simulation.

  

• Set to zero

• Selecting this option causes the Signal Builder block to output zero for the remainder of the simulation.

  

Sample time

Determines whether the Signal Builder block outputs a continuous (the default) or a discrete signal. If you want the block to output a continuous signal, enter 0 in this field. For example, the following display shows the output of a Signal Builder block set to output a continuous Gaussian waveform over a period of 10 seconds.

If you want the block to output a a discrete signal, enter the sample time of the signal in this field. The following example shows the output of a Signal Builder block set to emit a discrete Gaussian waveform having a 0.5 second sample time.
