Requirement analysis is important for developing and implementing safety critical systems. The system identified is intended to reduce the risks and fulfils earlier discovered safety requirements. A single error during requirements gathering can generate serious software faults. Software inspection is done for the verification and validation process. Traceability of requirements is carried out to avoid later risk factors. Fault tolerant architectures are used for the efficient behaviour of safety critical systems. This integrated environment is proposed for developing the safety critical system. The computer aided tool is used for the integrated environment.
