  • Observer Reference block


The Observer Reference block references a separate model called the Observer model, which houses your verification subsystem. Connect the Observer Reference block to Simulink® models without signal lines to wirelessly debug and test the design of the system.


The Observer Reference block does not have inports or outports. Signals are mapped to the Observer Model through the Observer Port block.
