  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.
