Analog testability analysis and fault diagnosis using behavioral modeling

This paper presents an efficient strategy for testability analysis and fault diagnosis of analog circuits using behavioral models. A key contribution is a new algorithm for determining analog testability. Experimentally, we determined the testability and faults of a fabricated 10 bit digital-to-analog converter modeled using the analog hardware description language, Cadence-AHDL. Also, we applied the testability analysis at the circuit level using SPICE sensitivity analysis.<<ETX>>
