Conventional software validation methods for real-time and reactive programs are not fully reliable. Considering complexity of formal verification and incompleteness of testing approaches, runtime verification approach is used. In this paper, Safety properties (after extracting from program requirement specification) are represented in Real-Time Logic (RTL) and fault tolerant module reaction are added to the program. Program monitoring module (which is realized by Functional, Timing and Deadline Aspects) is weaved to the program code. The enriched program executes in the environment. The monitoring module verifies program behavior by considering the specified safety properties and when any violence of a property is detected, then the specified reaction (Fault Tolerance) activates and navigates the program to a safe state.
