Create Mask Parameter Structure to Simplify Tuning and Data Management

Open Live Script

This example shows how to create a structure of mask parameters and refer to the structure from a mask to simplify tuning and data management.

Create structure of mask parameters to:

  • Manage simulation data

  • Iteratively tune mask parameters between model simulations and code generation

  • Separate the parameter tuning process from the modifying the model or mask dialog box

Use mask parameter structures in your simulation or code generation workflow:

Use the argument ParameterValueStruct in get_param and set_param commands to create and associate struct containing parameter names and current values for masked blocks.

Open the model.

open_system("slexMaskingBasic")

The example model contains a masked block named mx + b with mask parameters Slope and Intercept.

Create a structure for the mask parameters of the block named mx + b. In general, to create a struct containing parameter names and current value for any masked block, use

structName = get_param(blockName or handle,"ParamtereValueStruct")

lineParams = get_param("slexMaskingBasic/mx + b","ParameterValuesStruct")
lineParams = struct with fields:
    m: 5
    b: 2

Associate the mask parameters of mx + b with the values in the structure lineParams.

set_param("slexMaskingBasic/mx + b", "ParameterValuesStruct",'lineParams')

The values of the mask parameters reference the fields of the structure lineParams in the mask dialog box.

Modify the value of the mask parameter Slope by modifying the structure field lineParams.m.

lineParams.m = 12;

The value of the mask parameter Slope is changed in the mask dialog box.

To modify the value of popup and check box parameters, use the set_param command after modifying the value in the mask parameter structure. Popup and checkbox parameters use the values from the structure instead of referencing the structure field names. In mx + b block mask, the check box parameter checkDatatype is "on". Set the checkDatatype parameter to "off".

lineParams.checkDatatype = "off";
set_param("slexMaskingBasic/mx + b", "ParameterValuesStruct",'lineParams')
