Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for achieving functional safety compliance using a recursive system layer analysis. A functional safety system uses a recursive method to sequentially analyze each layer of a target environment from a bottom layer (e.g., IP layer) to a top layer (e.g., system layer). If a target diagnostic coverage level is not achieved at a given layer, the functional safety system attempts to achieve the target diagnostic coverage level at the next layer based on the residual faults from the lower layer. At the top layer, the functional safety system may apply the context of the target environment to reduce the scope of the coverage analysis based on the given application. The functional safety system may also use the context of the target environment to the reanalyze the lower layers as needed.
