A Software-Based methodology for In-Field Power-on Self-Test of Safety-Critical Timer Modules

This work proposes a set of time and memory bounded Software-Based methodologies for power-on Self test (or key-on self test) of timer modules for safety critical domains, such as automotive and aerospace. Fault simulations campaigns are conducted on an industrial device and intersected with Logic BIST at key-on fault coverages for Stuck-At and Transition Delay fault models. In order to show the portability of the proposed methodology to a smaller technology node, experimental results are presented on Stuck-At and Transition Delay fault models for an open source System-on-Chip.
