This course introduces contemporary design of VLSI circuits. The material covers nanometer CMOS technology and scaling, design principles of digital circuits, as well as designs of core VLSI building units. Examples include arithmetic circuits, the memory system, I/O circuitries, and other important circuits for VLSI system integration. Implementations in CMOS will be overarched by considerations of key design metrics, such as timing, power, and reliability. This course is a project-oriented class, which requires students to design and layout VLSI circuits and sub-systems using commercially available design tools.
