An ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science, and mathematics2. An ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors3. An ability to communicate effectively with a range of audiences4. An ability to recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts5. An ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives6. An ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions7. An ability to acquire and apply new knowledge as needed, using appropriate learning strategies.Computer UsageStudents use DLS, Simple Scalar and other simulators to analyze the system or a component performance. Students use HDL and CAD tools and platforms to design a component or a system.
