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.

(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.

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:

- 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:
