On coverage of timing related faults at board level

In this paper, we demonstrate a clear gap in board level test coverage under category of timing related faults (TRFs). Although there are techniques that are capable to detect TRFs, there is no fault coverage metrics to quantify the quality of these techniques. To do that, we propose an easy-to-implement interconnect-level fault model extension towards TRFs. This extension can be integrated into existing test coverage models providing additional information on coverage of timing-related faults.
