Fault injection emulation for field programmable analog arrays

We present a practical and economical method for physical fault insertion in analog circuits using field programmable analog arrays (FPAAs) for use in the development and evaluation of manufacturing and system-level tests for analog and mixed-signal integrated circuits and systems. The method involves the manipulation of configuration bits used to program the FPAA to emulate catastrophic faults (shorts and opens) and parametric faults (component values outside of acceptable ranges) in the FPAA during operation of the analog circuitry.
