论文摘要
单通量量子（SFQ）逻辑家族是一种新型的数字逻辑，因为它提供了超快速和节能的电路。对于大规模的SFQ电路设计，与CMOS逻辑相反，由于逻辑类型，时序约束和电路体系结构的差异，需要专门的电子设计自动化（EDA）工具。为了提高SFQ电路的整体性能，应在布局设计期间应用有效的路由算法，以执行准确的定时调整以固定违规行为并优化关键路径。因此，提出了混合的Josephson传输线和被动传输线路由框架。它由四个主要模块组成，并根据给定的布局放置对潜在的计时性能进行探索。提出的路由工具在七个测试台电路上进行了证明。获得的结果表明，工作频率大大提高，每个电路的所有持有违规都被消除。
The Single Flux Quantum (SFQ) logic family is a novel digital logic as it provides ultra-fast and energy-efficient circuits. For large-scale SFQ circuit design, specialized electronic design automation (EDA) tools are required due to the differences in logic type, timing constraints and circuit architecture, in contrast to the CMOS logic. In order to improve the overall performance of an SFQ circuit, an efficient routing algorithm should be applied during the layout design to perform accurate timing adjustment for fixing hold violations and optimizing critical paths. Thus, a hybrid Josephson transmission line and passive transmission line routing framework is proposed. It consists of four main modules and an exploration of the potential timing performance based on the given layout placement. The proposed routing tool is demonstrated on seven testbench circuits. The obtained results demonstrate that the operating frequency is greatly improved, and all the hold violations are eliminated for each circuit.
