For tile physical defects occurring in CMOS circuits which are not handled well by voltage-based testing, current testing is remarkable testing technique. Fault models based on defects must accurately describe the behaviour of the circuit containing the defect. In this paper, An efficient collapsing algorithm for fault models often used in current testing is proposed. Experimental results for ISCAS benchmark circuits show the effectiveness of the proposed method in reducing the number of faults that have to be considered by fault collapsing and its usefulness in various current based testing models.
