Problems of verifying and validating real time systems
In the video, the car starts out driving too close to the left-hand side of the curve.
The Tesla is going so slowly that the driver worries aloud about the semitruck behind him.
As the Tesla goes through the curve, it is way off into what NASCAR calls the marbles, small bits of debris that come off tires and vehicles and accumulate near the outside wall of a track.
With respect to real-time computing, there are several important V&V issues in the design of real-time software system.
One of the important features of real-time systems is the critical nature of the software execution speed with reference to external events.
In this respect V&V is a concept which is not to be built in the hardware system as, however, the case is reverse for the concept of reliability.
On the other hand, an independent V&V effort can be implemented on a software so that quality can be built into the software by means of provisons that the features, with respect to the above-stated items, of V&V issues are favorably implemented in the life-cycle of real-time software development.
