Based on input current, calculation is made using it and previous membrane potential. If current membrane potential is above pre-set threshold then spike!
After reset, input some current and see what happens. Should see an increase on output and possibly a spike eventually.
A current input of 100 after 20 cycles should produce a spike.
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | clk_i is the clock | nu_o is the next membrane potential | msb bit of uio_oe is connected to spike_o |
| 1 | current_i is the current input to the LFI neuron | spike_o is the single bit to show when the neuron is firing | |
| 2 | rst_n is for reset | ||
