statemachine

This module implements a Finite State Machine (FSM), or State Machine in short. The FSM is composed of states and transitions between them. These need to be specified by the client.

Usage

Have a look at statemachine_test.v for usage examples. On each run(), the possible transitions from the current state are evaluated.

If the condition (specified by the client as a handler function) is true, then:

  • the client-specifid on_exit() handler from the current state is called.
  • the client-specifid on_entry() handler of the new state is called.
  • the client-specifid on_run() handler of the new state is called.
