The Ravenscar Profile is an exciting development for the Ada community since it provides, for the first time in the history of our industry, support for deterministic, multi-tasking programming as an integral part of a standardized language. Despite its many advantages, the profile leaves several areas where behaviour is implementation defined and can result in run-time errors; this is unfortunate in a profile aimed clearly at the critical systems market. The SPARK language is a well-established sequential Ada subset that avoids ambiguity and allows all language rule violations to be detected prior to execution. The authors showhowthe principles of SPARK have been successfully extended to encompass the Ravencar Profile thereby statically eliminating the profile's problematic areas. The result should allow concurrent Ada programs to be constructed with the same degree of rigour that is now possible using sequential SPARK.
