1. A method of scalable routing of connections in a synaptic time-multiplexed (STM) neuromorphic network, the method comprising attempting to route connections between pairs of nodes of a fully connected neural network, a successfully routed connection defining a signal path between a pair of nodes in a first time slot of a synaptic time multiplexing cycle of the STM neuromorphic network; and repeating an attempt to route connections of the fully connected neural network for each node pair which attempting to route connections failed to produce a defined signal path between the nodes of the pair, wherein a successfully routed connection produced by repeating an attempt to route connections defines a signal path between the nodes of the pair in a second time slot of the STM neuromorphic network.
