SIGNATURE ANALYZER OF BUILT IN SELF TEST FOR ANALYZING STUCK AT FAULTS IN COMBINATIONAL LOGIC ICS
Daftar Isi:
- A signature analyzer of a built-in self test circuit is proposed to analyze stuck-at-faults occurring at input and output gates inside a combinational logic IC (Integrated Circuit). There are two types of the faults, namely stuck-at-1 and stuck-at-0. Logic values of the gate may be 1 and 0 values caused by stuck-at-1 and stuck-at-0, respectively. The test circuit consist of a pattern generator, multiplexers, demultiplexers, and the signature analyzer. In this paper, a feasibility of the test circuit is simulated using a Modelsim simulator. The IC of XXX0832 distributed by Nexperia.Co.Ltd is used as a CUT (Circuit Under Test). Simulation results show that the faults inside it may be analyzed to be detected
