1. What is CAV?

Computer-Aided Verification (CAV) refers to the use of algorithms and software tools to automatically check the correctness of hardware and software systems. The main goal of CAV is to ensure that these systems adhere to their specifications, thereby preventing errors that could lead to catastrophic failures.

1.1 Definition and Scope

The scope of CAV encompasses various aspects of system design, including:

• Model checking
• Theorem proving
• Static analysis
• Dynamic analysis

1.2 Key Objectives

The key objectives of CAV include:

• Identifying design flaws early in the development process
• Reducing testing time and costs
• Enhancing system reliability and safety

2. History of CAV

The origins of CAV can be traced back to the early days of computer science. Key developments in formal methods and logic have significantly influenced the evolution of CAV.

2.1 Early Developments

In the 1970s and 1980s, researchers began exploring formal verification techniques, leading to the establishment of model checking as a viable method for verifying finite-state systems.

2.2 Milestones in CAV

Several milestones marked the advancement of CAV, including:
