| Popis: | We designed a single-flux-quantum (SFQ) 2×2 unit switch. It is the main component of the SFQ Banyan packet switch we are developing. The unit switch transfers two input packets to the outputs according to their destination addresses. Our unit switch includes a controller that decodes packet headers and addresses. The controller also detects blocking, which occurs if both input packets have the same destination address. We designed the unit switch by using a cell-based design method. A new tool was developed to analyze the timing between data and clock signals for large-scale SFQ circuits. The 2×2 unit switch consists of about 730 cells and 2400 Josephson junctions. It was fabricated by using an NEC standard Nb process. We tested it and confirmed its correct operations. |
