Fault diagnosis for linear analog circuits
This paper presents a novel scheme to diagnose single and double faults for linear analog circuits. The scheme first proposes a simple transformation procedure to transform the tested linear analog circuit into a discrete signal flow graph, then constructs "diagnosing evaluators", which model the faulty components, to form a diagnosis configuration to diagnose the faults through digital simulation. This saves much computation time. Furthermore, a simple method to un-power the OP's is also proposed to differentiate equivalent faults. The scheme can diagnose faults in passive components as well as faults in OP's.

Comprehensive interconnect BIST methodology for virtual socket interface
Comprehensive interconnect BIST achieves 100% fault coverage on net faults and driver faults without any prerequisitive assumption on the connection configuration and the fault-free and faulty behavior of the interconnects. Guidelines are derived and structure maps are proposed to achieve the goal.

Configuration free SoC interconnect BIST methodology
Three-state drivers are modified to exhibit wired-logic properties in test mode. It does not only make interconnects random pattern testable but also improves the fault coverage and shortens the test length simultaneously.

Robust fuzzy control of nonlinear systems using shape-adaptive radial basis functions
Recently, various adaptive fuzzy control schemes have been proposed to deal with nonlinear systems whose dynamics are poorly understood by using the parameterized fuzzy approximators. However, most of the schemes presented so far can only tune the parameters, which appear linearly in the parameterized fuzzy approximators. The major disadvantage is that the desired approximation error may not be warranted and consequently, the control performance could be influenced. In this paper, we tune not only the linear parameters but also the parameters, which appear nonlinearly in the fuzzy approximators, to reduce the approximation error and to improve control performance. The proposed adaptive controller ensures global stability of the overall adaptive system and achieves desired tracking.
