Abstract/Summary
The project presents the design, fabrication, and implementation of a PCB test bench that interfaces with a custom VLSI chip designed to emulate the neural activity of a Central Pattern Generator (CPG). The test bench provides a precise and reliable platform for supporting signal operations and validating neuromorphic functionality. The design integrates both analog and digital circuitry to provide stable biasing, signal routing, and measurement access for chip characterization. The incorporation of op-amp buffers and adjustable potentiometers enables precise voltage tuning, resulting in controlled neuron-like behavior within the custom IC. The two-layer PCB supports modular interfacing with standard laboratory instruments and facilitates comprehensive testing of both analog and digital signals. The project combines circuit design, mixed-signal testing, and hardware validation to bridge theoretical neuromorphic concepts with practical electronic implementation. Engineering principles are applied to create a robust test bench intended to facilitate further progress in neuromorphic circuit development.
