Fault models are indispensable for many EDA tasks, so as for design and implementation of quantum hardware. In this article, we propose a fault model for superconducting quantum systems. Our fault model reflects the real fault behavior in control signals and structure of quantum systems. Based on it, we conduct fault simulation on controlled-Z gate and quantum circuits by QuTiP. We provide fidelity benchmarks for incoherent faults and test patterns of minimal test repetitions for coherent faults. Results show that with 34 test repetitions a 10% control noise can be detected, which help to save test time and memory.
