Implementation pitfalls

• Different ways to express similar things
  • scalar values
    • time-based (Simulink)
    • event-based (SimEvents)
    • physical-valued (Simscape)
  • events
    • sample time hit
    • rapid value change ("edge")
    • trigger signal
    • function call
  • has to be fixed for layer interface
• Physical modeling
  • needs many signal converters and reference points
  • clutter model → destroy simple structure
  • remedy: hide them in subsystems
