Submodules¶

spynnaker.pyNN.models.neuron.additional_inputs.abstract_additional_input module¶

class spynnaker.pyNN.models.neuron.additional_inputs.abstract_additional_input.AbstractAdditionalInput(data_types)[source]¶

Bases: spynnaker.pyNN.models.neuron.implementations.abstract_standard_neuron_component.AbstractStandardNeuronComponent

Represents a possible additional independent input for a model.

Parameters:	data_types – A list of data types in the component structure, in the order that they appear

spynnaker.pyNN.models.neuron.additional_inputs.additional_input_ca2_adaptive module¶

class spynnaker.pyNN.models.neuron.additional_inputs.additional_input_ca2_adaptive.AdditionalInputCa2Adaptive(tau_ca2, i_ca2, i_alpha)[source]¶

Bases: spynnaker.pyNN.models.neuron.additional_inputs.abstract_additional_input.AbstractAdditionalInput

add_parameters(parameters)[source]¶

Add the initial values of the parameters to the parameter holder

Parameters:	parameters (`spinn_utilities.ranged.range_dictionary.RangeDictionary`) – A holder of the parameters

add_state_variables(state_variables)[source]¶

Add the initial values of the state variables to the state variables holder

Parameters:	state_variables (`spinn_utilities.ranged.range_dictionary.RangeDictionary`) – A holder of the state variables

get_n_cpu_cycles(n_neurons)[source]¶

Get the number of CPU cycles required to update the state

Parameters:	n_neurons (int) – The number of neurons to get the cycles for
Return type:	int

get_units(variable)[source]¶

Get the units of the given variable

Parameters:	variable (str) – The name of the variable

get_values(parameters, state_variables, vertex_slice, ts)[source]¶

Parameters:	parameters (`spinn_utilities.ranged.range_dictionary.RangeDictionary`) – The holder of the parameters state_variables (`spinn_utilities.ranged.range_dictionary.RangeDictionary`) – The holder of the state variables vertex_slice – The slice of variables being retrieved
Returns:	A list with the same length as self.struct.field_types
Return type:	A list of (single value or list of values or RangedList)

has_variable(variable)[source]¶

Determine if this component has a variable by the given name

Parameters:	variable (str) – The name of the variable
Return type:	bool
