Single-fault fault collapsing analysis in sequential logic circuits

This paper studies single-fault fault collapsing in sequential logic circuits. Two major phenomena, self-hiding (SH) and delayed reconvergence (DR), which arise from the existence of feedback paths and storage elements in sequential circuits, are analyzed and found to cause the dominance relationship which is valid in combinational circuits but no longer valid in sequential circuits. A fault-co...

Exact Functional Fault Collapsing in Combinational Logic Circuits

Fault equivalence is an essential concept in digital VLSI design with significance in many different areas such as diagnosis, diagnostic ATPG, testability analysis and synthesis. In this paper, an efficient procedure to compute exact fault equivalence classes of combinational circuits is described. The procedure consists of two steps. The first step performs structural fault collapsing and uses...

A Fault Analysis in Reversible Sequential Circuits

Abstract— In this paper, the researchers propose the design of reversible circuits using reversible gates. Reversible logic is implemented in reversible circuits. Reversible logic is mostly preferred due to less heat dissipation. Conservative logic gates can be designed in any sequential circuits and can be tested using two test vectors. The significance of proposed work lies in the design of r...

Fault Collapsing in Digital Circuits Using Fast Fault Dominance and Equivalence Analysis with SSBDDs

The paper presents a new method and an algorithm for structural fault collapsing to reduce the search space for test generation, to speed up fault simulation and to make the fault diagnosis easier in digital circuits. The proposed method is based on hierarchical topology analysis of the circuit description at two levels. First, the gate-level circuit will be converted into a macro-level network...

EGFC: An exact global fault collapsing tool for combinational circuits

Fault collapsing is the process of reducing the number of faults by using redundance and equivalence/dominance relationships among faults. Exact fault collapsing can be easily applied locally at the logic gates, however, it is often ignored for most circuits, due to its high demand of resources such as execution time and/or memory. In this paper, we present EGFC, an exact global fault collapsin...
