Index increase in analog fault simulation

One possibility for fault diagnosis of analog circuits and analog system components is the use of an analog fault simulator. In this process, various faults (e.g. short circuit or open circuit) are injected into the circuit and the behavior of the modified circuit is simulated. Injecting a fault into an existing circuit can increase the index of the corresponding network equations.
