Software Tools for Flux Trapping and Magnetic Field Analysis in Superconducting Circuits

We have recently developed and reported methods with which we analyze the effects of external magnetic field and flux trapping on superconducting electronic circuits. Here, we show how the methods can be turned into tools and discuss verification of the analysis results. We present robust and repeatable post-layout verification methods and show examples of magnetic field and flux trapping analysis. This paper makes it possible to analyze the effects of static magnetic fields and trapped flux on circuit operation.
