Wrap To Zero

Set output to zero if input is above threshold

  • Library:
  • Simulink / Discontinuities

    HDL Coder / Discontinuities


The Wrap To Zero block sets the output to zero when the input is above the Threshold value. When the input is less than or equal to the Threshold, then the output is equal to the input.

Output signal set to the input signal value or zero. The data type of the output is the same data type as the input.


If the input data type cannot represent zero, parameter overflow occurs. To detect this overflow, go to the Diagnostics > Data Validity pane of the Configuration Parameters dialog box and set Parameters > Detect overflow to warning or error.
