| Abstract(in English) | In this research, we propose a routing method with wire ordering based on timing slack allocation for SFQ circuits. In proposed method, clock nets are routed first. Next, we group clocked gates by its level and route data nets for each level. The level of a gate is the number of gates on the path from the external input to a pin of the gate. Before the data net routing, we calculate timing slacks and sort wires ordering by timing slack. Each net is routed incrementally in order of global/detailed routing. Using timing and layout information of routed nets, the wire ordering and the congestion map are updated dynamically. In the experiments, the proposed method obtained routed layouts with 44.5% fewer delay elements for timing adjustment on average compared to a conventional method. |
