The safety-related requirements are a part of the system requirements which are inputs to the software life cycle processes. These system requirements are developed from systems architecture. The system requirements are developed on each functional area applications. The safety requirements are assessed at the individual functional areas. This white paper proposes a solution to develop safety requirements for functional areas interfaces and method to flowdown software requirements throughout product lifecycle. While developing requirements from system requirements to high level and low level requirements, the requirements would be completely analyzed for safety perspective. The advantage of this proposal is that the functional modules interface requirements are analyzed and captured from safety perspective. Reuse of the product extracts specific safety related requirements at each functional level as the requirements are developed at each interface modules. This leads to extensive verification of interface requirements along with system requirements which would leads to a safer product.
