Subsystem

Group container that wraps a sub-circuit and can run at a faster effective time-step than its parent (multi-rate). Cross-boundary signals must use From/GoTo (control) or transmission lines (electrical).

This component renders as a dynamic-size container; see the editor for its on-canvas appearance.

This component has no wired ports — see Named inputs / outputs below if any.

Parameters

Name	Label	Type	Default	Units	Description
num_iterations	Iterations per outer step	int	1	—	Substeps per outer step (multi-rate). N=1 = same rate as the parent. N>1 = subsystem runs N times per parent step with dt_inner = dt_parent / N. Siblings with the same N share a rate group.
hi_res_monitoring	Hi-res monitoring	enum (disabled / enabled)	1	—	When on, observables in this subsystem's rate group emit one sample per inner substep; when off, one per outer step. Default on.
