“Verify Model at Default Simulation Snapshot Time” on page 14-6

Magnitudes (dB)

Magnitude values for one or more upper magnitude bound segments, specified in

decibels.

Specify the corresponding frequencies in Frequencies (rad/sec) on page 16-22.

Settings

Default:

[] for Bode Plot block

[-20 -20] for Check Bode Characteristics block

Must be specified as start and end magnitudes:

• Finite numbers for a single bound with one edge


• Matrix of finite numbers for a single bound with multiple edges

For example, type [–10 –10; –20 –20] for two edges at magnitudes [–10 –10] and [–20 –

20].

• Cell array of matrices with finite numbers for multiple bounds

Tips

• To assert that magnitude bounds are satisfied, select both Include upper magnitude
  bound in assertion on page 16-21 and Enable assertion on page 16-32.


• You can add or modify magnitudes from the plot window:
  
  
  • To add a new magnitude, right-click the plot, and select Bounds > New Bound.
    Select Upper gain limit in Design requirement type, and specify the
    magnitude in the Magnitude column. Specify the corresponding frequencies in the
    Frequency column.
  
  
  • To modify the magnitudes, drag the bound segment. Alternatively, right-click the
    segment, and select Bounds > Edit Bound. Specify the new magnitudes in the
    Magnitude column.
  
  
  
  

You must click Update Block before simulating the model.
