The experimental set-up for the simulations. (A) To create the reference data, the C model is executed (with STDP) and the connectivity matrix A and delay matrix D are saved. Then five times are selected, for which the weight matrix W(t_i) is recorded. Along with the input stimulus to the network I(t), these matrices determine five network states for later comparison. These initial conditions are then set for an implementation of the C model (B) and for the SpiNNaker model (C), both without STDP. This results in the network spiking activity recordings $S_i^{\text{C}}(\mathit{W}(t_i),t)$ and $S_i^{\text{NM}}(\mathit{W}(t_i),t)$ for five simulation runs for the C model and the SpiNNaker model, respectively.
