Computer Engineering

This course teaches methods for design and synthesis of hardware at the logic level. It covers optimizations for designing low power, low cost and high performance multi-level logic. It covers design verification, manufacturing test and technology mapping. Multi-level combinational logic theory, sequential logic models, binary decision diagrams, finite state machines and unate function theory are covered. The course includes exposure and experience with CAD tools that do synthesis, verification and test.

This course is a technical elective for electrical and computer engineering, computer science and mathematics majors. The goals are to impart advanced theoretical concepts in the design of digital logic circuits that will prepare a student for graduate research work in logic optimization, simulation and testing, asynchronous circuits, and finite-state machine theory.
