The input clock is connected with the inputs of the neuron clusters. The bi-directional pins are provided where external input stimulus could be provided. The raster spiking plots are generated to observe the variability of different spiking neuron clusters.
Provide input clock frequencies to the neuron clusters and observe the output through the oscilloscope.
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | CLOCK Attached to the on-board clock | OUT0 on-board CLOCK | D0 OUTPUT from a 1-bit FF |
| 1 | INO Connected with a 1-bit FF | OUT1 Output from the LFSR | D7 OUTPUT from (1x3x3) cluster |
| 2 | IN1 external input to the MUX | OUT2 Output from 2-bit FF | D1 OUTPUT from the (5X5) cluster |
| 3 | IN2 Enable signal to the MUX | OUT3 Output from 3-bit FF | D2 OUTPUT from (6x6x6) cluster |
| 4 | IN3 Connected as a SELECT pin for the MUX (connected with (1x3x2x1) and (6x6x6) cluster. | OUT4 Output from 4-bit FF | D3 OUTPUT from (6x6x6) cluster |
| 5 | IN4 Input to the (6x6x6) cluster | OUT5 Output from 5-bit FF | D4 connected as an OUTPUT pin from either the (6x6x6) cluster or the (1x3x2x1) cluster (where IN3 is the input select pin) |
| 6 | IN5 Input to the (6x6x6) cluster | OUT6 Output from 6-bit FF | D5 INPUT to the (6x6x6) cluster |
| 7 | IN6 Input to the (6x6x6) cluster | OUT7 MUX output) | D6 INPUT to the (6x6x6) cluster |
