. Spin is is a tool for analyzing
the logical consistency of concurrent systems,
specifically of data communication
protocols
. Spin uses a modeling language
called Promela (Process Meta Language) to
describe the
behavior and interaction between different processes, invariants
can be
represented as assertions.
. Spin works on the Promela
description and checks for absence of deadlocks,
unspecified
receptions, and unexecutable code.
. Spin is designed to attack
software problem, but is also helpful in logical
design,
because it provides a method of formal verification.
