Real-time specification inheritance anomalies and real-time filters

open access: yes, 1994
Real-time programs are, in general, difficult to design and verify. The inheritance mechanism can be useful in reusing well-defined and verified real-time programs. In applications developed by current real-time objectoriented languages, however, changing application requirements or changing real-time specifications in subclasses may require excessive ...
