This web page is devoted to gate-level simulation of the LC-2 processor, described extensively in Yale N. Patt and Sanjay J. Patel textbook "Introduction to Computing Systems (from bits & gates to C & beyond)".

The DigLC2 simulator started as a support tool for an introductory architecture course (in French, september-december 2001) at École Polytechnique, France.

Lectures: Olivier Temam.

Practical sessions: Albert Cohen and Olivier Temam.

Simulator: Albert Cohen.
