Abstract :
In-this paper, we present an efficient and accurate IDDQ fault modeling technique for digital CMOS circuit. Both the normal and faulty “current” behaviors of a CMOS digital circuit can be described by this model. Also the parasitic capacitive and inductive parameters can be emulated. A formal method for creating this model from any given CMOS circuit is obtained. Using this model, circuit design of built-in current sensors (BICSs) can be designed and validated without introducing the actual circuit under test (CUT) which implanted a fault. Experimental data for the application to the design of BICSs is also given
