| Outline of Final Research Achievements |
We propose fault-based BIST(Built-In Self Test) schemes for Analog part of AMS (Analog Mixed-Signal) system LSI. The BIST systems can be used throughout life time of LSIs, from fabrication process to the system's operation. Motif circuits of analog system to design BIST systems are Voltage/Current reference generator and delta-sigma modulator.
The BIST systems are based on transient response of circuits and fault coverage of Catastrophic faults, such like open/short fault of circuit elements, are about 85% to 96% with reasonable area overhead. We also find the BIST systems based on Chaotic oscillation can cover Parametric
faults.
