Promela

Promela (Process Meta Language) is a formal modeling language used to describe and analyze the behavior of complex, concurrent systems, such as communications, protocols, or distributed applications. It allows developers to create detailed models of system components, including their possible states and interactions. These models can then be checked using the SPIN model checker, which verifies correctness properties like safety and liveness, helping identify potential errors before actual implementation. In essence, Promela provides a precise way to simulate and analyze how parts of a system work together to ensure reliability and correctness.
