Notebook 9: Model Checking Basics

Introduction to Model Checking algorithms in formal verification. Understand how systems are verified against temporal logic specifications automatically.

Model Checking Basics

Model Checking is the core automated technique studied in Verification and Validation. It is the algorithmic process of determining whether a given finite-state model of a system meets a given formal specification (typically expressed in temporal logic like LTL or CTL).

Course Materials for Model Checking

The theoretical foundations of model checking algorithms, state-space explosion problems, and practical approaches are detailed in the course notes.

Key concepts covered:

• Kripke Structures & Transition Systems: Modeling hardware and software systems.
• Automata-Theoretic Approach: Intersecting the system model with the negation of the specification automaton.
• On-the-fly Verification: Checking properties without building the entire state space upfront.
• Complexity: Why model checking is computationally hard (PSPACE-complete for LTL) and how abstractions help.
