Student OutcomesIn the parentheses for each Student Outcome:
"P" for primary indicates the outcome is a major focus of the entire course.
“M” for moderate indicates the outcome is the focus of at least one component of the course, but not majority of course material.
“LN” for “little to none” indicates that the course does not contribute significantly to this outcome.
1. ( P ) An ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science, and mathematics
2. ( M ) 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 factors
3. ( P ) An ability to communicate effectively with a range of audiences
4. ( LN ) 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 contexts
5. ( M ) 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 objectives
6. ( P ) An ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions
7. ( M ) An ability to acquire and apply new knowledge as needed, using appropriate learning strategies.
Strategic Performance Indicators (SPIs)
- apply their knowledge from ECE 2030 to practical laboratory experience in digital computing systems. [6, 8]
- apply the concepts of basic combinational logic circuits, sequential circuit elements, and programmable logic in the laboratory setting. 
- develop familiarity and confidence with designing, building and testing digital circuits, including the use of CAD tools. [1, 7, 11]
- develop team-building skills and enhance technical knowledge through both written assignments and design projects. [2, 13]
Laboratory projects will use a PC-based CAD environment that supports schematic capture, logic simulation, and HDL-based logic sysnthesis on FPGAs (field-programmable gate arrays). Small-scale integrated circuits will be used for early labs, then HDL-based logic synthesis on FPGA-based design boards will be used for more advanced design implementations, including exposure to mixed design-entry methods. The semester will culminate with design projects specified and undertaken by teams of three to five students. Technical writing skills are developed through laboratory reports, project documentation, and an oral presentation.
