The level and degree (usage extremes) of the regression tests depend on what the safety requirements, warrenty requirements, customer, software quality assurance, etc. demand versus time, equipment and money resources. Yes it is a level of gray, not black and white. > Some other approaches might be taken, a good one is (IMHO) static >scheduling and checking of time constraints, which is possible if you >reduce the scope of the language the code is written in (e.g. no infinite >loops allowed). It would be a difficult paradigm shift for my co-workers and I to give up using tasks with infinite loops that wait for events to be signaled or for certain amounts of time to elapse. Of course this also requires the ability to detect task "cycle slips". I've been doing this for the last 12 years using both Jovial and Ada83 and have been able to deploy reliable hard real time systems. This is not just a language issue as RTE's and RTOS's can be used by a lot of different languages. I'm trying to visualize just what this approach you are talking about would involve that does not use any loops. Guess I have to copy down one of the papers you cite. _____________________________________________________________________ Robert S. White -- An embedded systems software engineer
