mural: A Formal Development Support System

Formal methods enable computer architecture and software design to be mathematically proved correct before they are implemented. The complexity and time-consuming nature of such proofs have limited the applications of formal methods in the main to defence and safety-critical applications. The mural project (a joint Alvey-funded project between M anchester U niversity and R utherford A ppleton L aboratories) has developed a software support system to help the user of formal methods. mural has cre
