Abstract
A method for determining fault types in a circuit design includes obtaining circuit elements, a first observation point of a first circuit element, and a first diagnostic point of a first safety circuit device. The method further includes determining a first cone of influence including a first subset of the circuit elements based on the first observation point. The first subset of the circuit elements includes the first circuit element. Further, the method includes determining a first safety cone including a second subset of the circuit elements based on the first diagnostic point. The first safety cone includes the first safety circuit device. The method further includes determining a fault type associated with the circuit elements based on an intersection between the first cone of influence and the first safety cone.
