Key Learnings

Understanding how to properly probe circuits, interpret oscilloscope traces, and use test equipment to diagnose embedded system operation. This foundation is essential for debugging and verifying circuit designs before and after fabrication.

Individual Assignment: EDA Design & Simulation

Use an EDA tool to design an embedded microcontroller system using parts from the inventory, check its design rules for fabrication, and simulate its operation. This assignment involves complete schematic capture, PCB layout, design rule checking, and circuit simulation.
