| 1. A method for performing a safety analysis in a system of a motor vehicle, the system including a plurality of components
linked by communication relationships, the components and the communication relationships forming a functional structure of
the system, the method comprising:
determining errors as a function of the functional structure;
analyzing error dependencies with respect to the functional structure;
tracking the error dependencies in the functional structure;
determining global effects of the errors;
determining errors which cause a malfunction of a component or a communication relationship;
determining measures for at least one of error detection and error control;
determining an achievable safety level and comparing the determined safety level with the selected safety level; and
restarting the method at the tracking as a function of the comparison until achieving the safety level.
