class spynnaker.pyNN.models.neuron.additional_inputs.AbstractAdditionalInput(structs: List[Struct], units: Dict[str, str])

Bases: AbstractStandardNeuronComponent

Represents a possible additional independent input for a model.

Parameters:

  • structs – The structures of the component

  • units – The units to use for each parameter
