Abstract(in English) | In recent years, approximate computing has been used in error-tolerant applications. Several approximation methods have been proposed for approximate multipliers by truncating the lower bits of the calculation result according to the positions of one-bits in the multiplier and the multiplicand. In testing approximation circuits, test time reduction can possibly be achieved by removing faults that affect only within the acceptable range of the calculation error. In this paper, to generate fewer test patterns for an approximate multiplier, the pseudo circuit restricting the fault propagation only to the lower bits is added in the test generation phase. As a result, the proposed test generation can attain about a 19.8% reduction in test patterns. |
