Abstract

The Quality Test Action Group (QTAG) was formed at the 1993 International Test Conference to define a standard for test fixture based off-chip quiescent current monitors for use in the production testing of CMOS Integrated Circuits. These quiescent current monitors will provide the IDDQ/ISSQ test instrumentation that is needed by the semiconductor industry. This paper proposes a standard serial interface to be used by ATE systems to communicate with the QTAG quiescent current monitors.
