How it works
Apply an input current injection to the IF neuron using switches. This gets added to a membrane potential. If the membrane potential exceeds the threshold, then it triggers a spike.
How to test
An 8-bit input current is applied to the IF neuron through the designated input (i.e., uio_in). The membrane potential of the IF neuron will respond to the applied input current. Larger currents will lead to a higher membrane potential. The neuron is designed to generate a spike when the membrane potential exceeds a certain threshold.
