Abstract

The semiconductor industry standard computer-aided-design (CAD) tool Cadence has been calibrated for a 3 /spl mu/m Niobium technology in order to design and build superconductive single flux quantum (SFQ) circuits. The top-down design methodology includes Verilog functional simulation, schematic capture, graphic layout, functional verification, design rule checking, electrical rule checking, and layout-vs.-schematic verification. This design framework has been used successfully at the University of Rochester in designing more than 15 elementary SFQ cells and three large scale digital and mixed-signal SFQ circuits, demonstrating significant improvement in both design efficiency and accuracy.
