Abstract ­ This paper presents new test and verification methodologies, in-
cluding design techniques targeting a neural oscillator. Because the output
signal of a neuron is chaotic, customized verification and test methodologies
are required. We have chosen to use MATLAB to verify our experimental re-
sults at a simulation level. In this paper we also describe a test circuit used
to perform electronic neuron IC testing. We investigate how a subthreshold
circuit can reduce power consumption. In our HSPICE simulations, we both
validate the proposed test circuit and verify the electronic neuron and synapse
Keywords ­ test methodology, chaotic, electronic neuron, chemical synapse,
subthreshold, tanh, comparator
