Detection of Low Power Trojans in Standard Cell Designs using Built-in Current Sensors
Basim Shanyour, Spyros Tragoudas · 2018
An approach to detect ultra-low-power no-payload Trojans by analyzing IDDT waveforms at each gate is presented. The approach uses a novel ATPG to insert small number of current sensors in order to analyze the behavior of individual gates at the IDDT waveform. The proposed method is assisted by a standard cell placement method that strengthens Trojan detection. Experimental results on the largest ISCAS'85, ISCAS'89 and ITC'99 benchmarks demonstrate that low-power no-payload Trojans are detected without any area overhead and with negligible performance degradation.
