Reening Reactive Systems in Hol Using Action Systems

  title={Reening Reactive Systems in Hol Using Action Systems},
  author={Joakim von Wright},
This report discusses how to re ne reactive systems using the HOL theorem prover. We show how Action Systems { the formal framework supported { can be formalised in HOL. We describe a simple re nement example. We also discuss how the work presented here can be used in connection with the Re nement Calculator, a tool supporting program re nement.
