A Beginner's Guide to TLA+: Exploring State Machines & Proving Correctness

TALK LEVEL: BEGINNER / INTERMEDIATE / ADVANCED

This talk introduces TLA+ by taking a small package from hex, examining its properties, modeling its behaviour as a state machine, creating TLA+ correctness and liveness specifications for it, and then using the TLA+ model checker to prove correctness. No prior exposure to formal methods like TLA+ or PlusCalc are necessary. A passing familiarity with state machines is recommended, but not required.

THIS TALK IN THREE WORDS

Formal

State

Machines

OBJECTIVES

  • Introduce TLA+ and its value
  • Illustrate conversion of a state machine to a TLA+ specification
  • Building and checking correctness and liveness models of that TLA+ specification

TARGET AUDIENCE

Developers interested in adding more rigour to their problem solving and more quickly surfacing design errors.
