Simulation Components ===================== There are two types of components that can be used in a tickit simulation, device simulations and system simulations. Device Simulation ----------------- Device simulations are the typical use case of a component. They encapsulate a device and any adapters for that device. .. figure:: ../../images/tickit-device-simulation-cpt.svg :align: center (See `DeviceSimulation`.) System Simulation ----------------- System simulation components are themselves entire tickit simulations. They contain their own device simulation components and a scheduler for orchestrating them. However, the scheduler in a system component acts as a slave scheduler which is driven by the master scheduler in the top level of the simulation it belongs to. .. figure:: ../../images/tickit-system-simulation-cpt.svg :align: center System simulations can also contain their own system simulation components allowing for the construction of reasonably complex systems. System simulations can be nested inside other components in the config so that the master scheduler's wiring is correct, for example: .. code-block:: yaml - type: examples.devices.trampoline.RandomTrampoline name: random_trampoline inputs: {} callback_period: 10000000000 - type: tickit.core.components.system_simulation.SystemSimulation name: internal_tickit inputs: input_1: component: random_trampoline port: output components: - type: tickit.devices.sink.Sink name: internal_sink inputs: sink_1: component: external port: input_1 - type: examples.devices.remote_controlled.RemoteControlled name: internal_tcp_controlled inputs: {} expose: output_1: component: internal_tcp_controlled port: observed - type: tickit.devices.sink.Sink name: external_sink inputs: sink_1: component: internal_tickit port: output_1 (See `SystemSimulationComponent`.) The Overall Simulation ------------------------------- A simulation containing both types of component will look something like this: .. figure:: ../../images/tickit-simple-overview-with-system-simulation.svg :align: center .. _DeviceSimulation: .. _SystemSimulationComponent:
