On design for I-DDQ-based diagnosability of CMOS circuits using multiple power supplies
This paper presents a novel approach to improving the I-DDQ-based diagnosability of a CMOS circuit by dividing the circuit into independent partitions and using a separate power supply for each partition. This technique makes it possible to implement multiple I-DDQ measurement points, resulting in improved I-DDQ-based diagnosability. The paper formalizes the problem of partitioning a circuit for this purpose and proposes optimal and heuristic based solutions. The effectiveness of the proposed approach is demonstrated through experimental results.
