Abstract
Manufacturing tolerances influence circuit parameters, and inductance is no exception. A computer application was developed to fully automate inductance calculation as part of a layout extraction suite. InductEx takes a GDSII layout file as input, finds the inductance ports, extracts structures, applies mask-to-wafer offsets and random process tolerances to the circuit structures, builds deck files that can be processed with FastHenry, and manages FastHenry - all autonomously. Results are presented for the simulated variation in inductance - both self and mutual, over hundreds of runs - in several common RSFQ structures in the Hypres 1 kA/cm2 process (with the latest tolerance values built in), even with the presence of moats. © 2005 IEEE.
