Displaying a Model's Nonvirtual Systems
The systems command prints a list of the nonvirtual systems in the model being debugged. For example, the Simulink clutch demo (clutch) contains the following systems:
sldebug clutch [Tm=0 ] **Start** of system 'clutch' outputs (sldebug @0:0 'clutch/Clutch Pedal'): systems 0 'clutch' 1 'clutch/Locked' 2 'clutch/Unlocked'Note
systems command does not list subsystems that are purely graphical in nature, that is, subsystems that the model diagram represents as Subsystem blocks but which Simulink solves as part of a parent system. In Simulink models, the root system and triggered or enabled subsystems are true systems. All other subsystems are virtual (that is, graphical) and hence do not appear in the listing produced by the systems command.
