Automated analog fault injection

1. A method for an automated analog fault injection, the method comprising:

creating a list of fault models for injection to an analog circuit;

adding a first fault placeholder to the analog circuit;

running fault simulations by replacing the first fault placeholder with a first analog fault model from the list of fault models; and

determining whether the first analog fault model is detected.

2. The method of claim 1 , further comprising generating a report of detection results.

3. The method of claim 1 , further comprising creating a list of fault locations, and adding a second fault placeholder to each fault location on the list of fault locations.

4. The method of claim 1 , wherein the creating a list of fault models includes specifying custom fault types.

5. The method of claim 1 , further comprising adding a short fault placeholder to the analog circuit, wherein the short fault placeholder is a fault short.

6. The method of claim 1 , further comprising adding a plurality of second fault placeholders at subcircuit ports.

7. The method of claim 1 , wherein the first fault placeholder is a voltage source having zero volt.

8. A system for an automated analog fault injection, the system comprising:

a list of fault models for injection to an analog circuit;

a plurality of fault placeholders for adding to the analog circuit; and

a processor configured to run fault simulations by replacing ones of the plurality of fault placeholders with a first fault model from the list of fault models, wherein the processor is further configured to determine whether the first fault model is detected.

9. The system of claim 8 , wherein the processor is further configured to generate a report of detection results.

10. The system of claim 8 , wherein the processor is further configured to create a list of fault locations, and wherein ones of the plurality of fault placeholders are added to each fault location on the list of fault locations.

11. The system of claim 8 , wherein the list of fault models includes custom fault types.

12. The system of claim 8 , further comprising a short fault placeholder for adding to the analog circuit, wherein the short fault placeholder is an open circuit.

13. The system of claim 8 , wherein the plurality of fault placeholders are voltage sources having zero volts.

14. One or more non-transitory computer-readable media with instructions stored thereon, the instructions when executed on a machine, cause the machine to:

create a list of fault models for injection to an analog circuit;

add a first fault placeholder to the analog circuit;

run fault simulations by replacing the first fault placeholder with a first fault model from the list of fault models; and

determine whether the first fault model is detected.

15. The non-transitory computer-readable media of claim 14 , wherein the instructions when executed on a machine, further cause the machine to generate a report of detection results.

16. The non-transitory computer-readable media of claim 14 , wherein the instructions when executed on a machine, further cause the machine to create a list of fault locations, and add a second fault placeholder to each fault location on the list of fault locations.

17. The non-transitory computer-readable media of claim 14 , wherein the creating a list of fault models includes specifying custom fault types.

18. The non-transitory computer-readable media of claim 14 , wherein the instructions when executed on a machine, further cause the machine to add a short fault placeholder to the analog circuit, wherein the short fault placeholder is a fault short.

19. The non-transitory computer-readable media of claim 14 , wherein the instructions when executed on a machine, further cause the machine to add a plurality of second fault placeholders at subcircuit ports.

20. The non-transitory computer-readable media of claim 14 , wherein the first fault placeholder is a voltage source having zero volt.
