Inside the Chip: From Product to Logic Circuit

Every digital product — a phone, a game controller, a medical monitor — runs on one or more chips. Open a chip far enough and you reach a network of named logic gates wired together: small elements that each take a few input bits and produce an output bit. Everything the product does at this level reduces to bits moving through that network.

This course works at the gate-network layer. You will not draw transistors or lay out silicon; you will describe what the gates should compute and confirm the description behaves correctly. That layer is where digital design starts, and the reasoning is portable: the same skills apply whether the circuit eventually ships as a custom chip or runs on an FPGA.

Keeping this picture in mind helps later lessons make sense. When you write a module that turns inputs into outputs, you are specifying one piece of that gate network — a piece a synthesis tool can turn into real hardware.
