I am trying to access data stored in a data dictionary from the Test Sequence Block. I've tried Simulink.data.dictionary.open but it is not supported for code generation.

@Doodle Baseball, To access data from a data dictionary in a Test Sequence block, define the variables as Simulink.Parameter or Simulink.Signal objects in the dictionary, and ensure they are in the model workspace or base workspace. The Test Sequence block can reference these variables directly if they are properly scoped and do not require run-time dictionary access (which is unsupported in code generation). Avoid using Simulink.data.dictionary.open during simulation.
