Masking a Model Block

You can use all techniques described in Roadmap for Masking Blocks to mask a model block, with one special requirement. If a mask specifies the name of the model referenced by a Model block, or by any Model block in a masked subsystem, the name of the referenced model must be given literally, rather than obtained by evaluating a workspace variable. This requirement exists because Simulink updates model reference targets before evaluating block parameters. Two ways to enforce the requirement are:

• Use a Pop-Up control to specify the name of the referenced model. Clear the control's Evaluate parameter to cause the control to provide a textual rather than a numeric value. This technique restricts the user to specifying one of a predefined set of models.

• Use an Edit control to specify the name of the referenced model. Clear the control's Evaluate parameter to cause the name that the user provides to be interpreted literally. This technique allows the user to specify any model as the referenced model.

See Defining Mask Parameters for information about defining Pop-Up and Edit controls.

Note   The mask workspace of a Model block is not visible to the model that it references. Any variables used by the referenced model must resolve to workspaces defined in the referenced model, or to the MATLAB base workspace.
