The focus of this project was on characterizing and assessing design problem solving in the area of digital circuit design. Think-aloud protocols and computer traces of subject problem-solving behavior were used to elucidate the cognitive processes involved in designing combinational and complex sequential circuits by: (1) studying the differences…

Biswas, Gautam; And Others – 1994
This report characterizes human problem solving in digital circuit design. Protocols of 11 different designers with varying degrees of training were analyzed by identifying the designers' problem solving strategies and discussing activity patterns that differentiate the designers. These methods are proposed as a tentative basis for assessing…
