| Abstract | Delay fault testing has proven to be a signifi- cant part of modern manufacturing testing. It has also be- come a source of overtesting due to detection of function- ally untestable faults by invalid transitions that would not occur during functional operation of the chip. There has been previous work in the field that identifies these faults allowing them to be removed from active fault lists from ATPG tools. However, due to the random fill of don't- care bits in test patterns, incidental detection of functio n- ally untestable faults becomes possible. In this paper, we propose a novel framework that will generate patterns us- ing any commercial ATPG that avoid detection of these functionally untestable transition faults. Previous meth- ods have required modification of the ATPG tool itself or designing a new ATPG to avoid such faults, making the immediate use of these tools very difficult. Our frame- work builds upon a commercial ATPG tool and modifies the netlist rather than the tool. By using the present function- ality of the ATPG tool and a modified netlist, pattern gener- ation is structurally constrained to avoid generating a pat- tern that will incidentally detect a functionally untestab le fault. The proposed minimally affects test coverage of func- tionally testable faults and does not significantly increas e the amount of effort needed by the ATPG tool. |
