How can you be sure that a hardware or software system is really correct?

 

The traditional approach to validating hardware and software systems is to do lots of testing.  Until recently, the alternative approach of using formal methods to prove correctness has not been practical.  One of the most important developments in this area is  easy-to-use model checking systems.  In this course we will study formal verification methods with an emphasis on model checking.  You will learn to use the SMV model checking system developed at Carnegie Mellon and use it to verify a significant hardware or software system.  This is your chance to learn about an emerging technology!  There will be three hours of lecture and an one hour of discussion each week.

 

Course Description

An introduction to current methodologies for verifying computer systems.  Topics covered include logic and theorem proving; modeling sequential, reactive and concurrent systems; transition systems; model checking methods; and controlling state explosion.  Special topics such as temporal logic, the mu-calculus, binary decision diagrams, Buechi automata, partial order reduction, and process algebras will be covered as time permits.  Students will complete a project using current model checking technology.

 

Prerequisites: EECS 281 and EECS 376.
