For R2025a and later

If the model reference only has a single instance, you can tune the parameter directly without creating a variable. See the release notes for R2025a: https://www.mathworks.com/help/slrealtime/release-notes.html?startrelease=R2025a&endrelease=R2025a&rntext=&groupby=release&sortby=descending&searchHighlight=#mw_008f8655-acd2-46ec-beda-92edace5180c

For R2020b - R2024b 

Only model-level parameters are supported for tuning with Speedgoat & Simulink Real-Time (SLRT). This means that you can tune workspace parameters, model arguments, and model instance parameters in referenced models. Tuning block parameters inside referenced models is no longer possible.

In order to tune parameters in referenced models, you can parameterize the references for the variables you want to control. For more information, see Parameterize Instances of a Reusable Referenced Model and Tunable Block Parameters and Tunable Global Parameters.

Note that structured parameters are supported as well, so it is possible to group many individual parameters together to simplify things.

For programmatic tuning with "setparam", note that the correct syntax for tuning parameters of reference model instances is:

>> tg = slrealtime;
>> tg.setparam({'top/model','sub/model'},'myParam',5);
