| Summary: | 碩士 === 國立臺灣大學 === 電子工程學研究所 === 103 === Waveform-accurate fault simulator is crucial for advanced technologies. This paper proposes a variation-aware waveform-accurate fault simulator. In our simulator, a signal waveform is represented by a bit sequence. Gate evaluation is performed by bitwise logic operations to process all transitions of a signal simultaneously. Monte Carlo simulation is performed for modeling process variation. The proposed simulator is demonstrated on crosstalk faults. Compared with traditional event-driven simulator, our simulator memorizes all waveforms for every signal so that crosstalk fault simulation can be quickly accomplished. The crosstalk fault activation percentage of our tool is 18% higher than floating mode delay model. Because of process variation, the result of simulation is a statistical fault coverage distribution instead of a deterministic value.
