According to the standard IEC 61508 fault insertion testing is required for the verification of fail-safe systems. Usually these systems are realized with microcontrollers. Fail-safe systems based on a novel CPLD-based architecture require a different method to perform fault insertion testing than microcontroller-based systems. This paper describes a method to accomplish fault insertion testing of a system based on the novel CPLD-based architecture using the original system hardware. The goal is to verify the realized safety integrity measures of the system by inserting faults and observing the behavior of the system.
