We designed a group of basic cells with high capability of fault detection and propagation, and confirmed their superior effectiveness on robustness, area overhead and circuit delay through designing real LSI. Also we found the way to evaluate the overall reliability of function units that have plural faults, and developed a technique to improve the reliability by replacing basic cells with XOR cells. Moreover, we developed an 8way-VLIW processor equipped with an instruction decomposition mechanism that is inevitable for implementing processors with such high reliable basic cells, and confirmed the decomposition mechanism is feasible from the view point of area, IPC and circuit delay.
