Abstract
A method for the specification of software for safety-critical applications is presented. It is based on a combination of the formal specification languages Z and real-time CSP. Guidelines for the development and validation of specifications are provided. Specification development is supported by reference architectures that can serve as templates for the specification of concrete systems. Validation is performed by inspection of specifications according to specific criteria and by proof of properties. These proofs rely on a common semantic model for the two languages. An example serves to illustrate the method.
