Introduction for Digital VLSI Design


The laboratory on the course ECL-523: Digital VLSI Circuit Design covers the basic CMOS integrated Circuit design, simulation, and testing techniques. Several tools from the Cadence Design System have been integrated into the lab to teach students the idea of computer aided design (CAD) and to make the VLSI experience more practical.

To fully appreciate the material in this lab course, the student should have a minimal background with the following computer systems, equipment, and circuit analysis techniques. Students should be familiar with the LINUX operating system.
