qGDR: A Via Minimization Oriented Routing Tool for Large-Scale Superconductive Single Flux Quantum Circuits

Single-flux-quantum (SFQ) circuit technologies are promising digital circuit technologies with high-speed and extremely low-power characteristics. However, heavy wire routing tasks are finished either by considerable human effort or by commercial routing tools with few physical considerations for the SFQ circuits. In this paper, we present an integrated global and detailed router for the SFQ circu...
