Testing SoC is a challenging task, especially when addressing complex and high- frequency devices. Among the different techniques that can be exploited, software-based selft-test (SBST) emerged as an effective solution, due some advantages it provides (no HW changes, at- speed testing, re-usability); however, the method requires effective techniques for(More)
Software-based self-test (SBST) is increasingly used for testing processor cores embedded in SoCs, mainly because it allows at-speed, low-cost testing, while requiring limited (if any) hardware modifications to the original design. However, the method requires effective techniques for generating suitable test programs and for monitoring the results. In the(More)
Caches are crucial components in modern processors (both stand-alone or integrated into SoCs) and their test is a challenging task, especially when addressing complex and high-frequency devices. While the test of the memory array within the cache is usually accomplished resorting to BIST circuitry implementing March test inspired solutions, testing the(More)
