Iddq testing

Iddq testing is a method for testing CMOS integrated circuits for the presence of manufacturing faults. It relies on measuring the supply current (Idd) in the quiescent state (when the circuit is not switching and inputs are held at static values). The current consumed in this state is commonly called Iddq for Idd (quiescent) and hence the name.
