INDEX: an inductance extractor for superconducting circuits

The authors present an extractor, INDEX, designed to extract superconducting circuits from layout. The inductances of the superconducting lines are calculated by a set of analytical models. These self- and mutual-inductance models are generated from a series of numerical simulations and a linear programming curve-fitting. INDEX is based on the MAGIC layout system. INDEX has been tested on a number of cases with good results. A two-junction superconducting quantum interference device (SQUID) was used as one test case.<<ETX>>
