VLSI

Integrated Circuit Design

The ECE Department at UMaine is a member of the Cadence University Software Program which provides students with access to a state-of-the-art integrated circuit design environment. ECE 547, VLSI Design and Layout, teaches the fundamentals of integrated circuit design and allows students to submit custom IC designs for fabrication through Mosis. Chips designed during this class are fabricated using a half-micron CMOS process.
