Description: In this system, we discuss the architecture, design, and testing of the
first 16-bit asynchronous wave-pipelined sparse-tree superconductor rapid
single flux quantum adder implemented using the ISTEC 10 kA/cm
2ADP2.1 fabrication process. Compared to the Kogge–Stone adder, our
parallel-prefix sparse-tree adder has better energy efficiency with
significantly reduced complexity (at the expense of latency) and almost no
decrease in operation frequency. The 16-bit adder core (without SFQ-to-dc
and dc-to-SFQ converters) has 9941 Josephson junctions occupying an area
of 8.5 mm 2. It is designed for the target operation frequency of 30 GHz
with the expected latency of 352 ps at the bias voltage of 2.5 mV. The adder
chip was fabricated and successfully tested at low frequency for all test
patterns with measured bias margins of +9.8 /− 10.7 . Platform: |

Description: Speculative variable latency adders have attracted strong interest thanks to their capability to reduce average delay compared to traditional architectures. This proposes a novel variable latency speculative adder based on Han-Carlson parallel- prefix topology that resulted more effective than variable latency Kogge-Stone topology. Platform: |

Description: 用hspice写了一个做了16bit kogge stone四层点操作的树形加法器静态逻辑网表，所有管子的尺寸按照0.25u的尺寸设计挂上测试文件跑以后逻辑没问题，但是按照拉贝尔那本书上讲的关于逻辑努力优化的方法优化，在输入级加了两级buffer，只对最长路径支路尺寸优化(Use HSPICE to write a 16bit kogge made stone four layer tree adder static logic netlist, all pipe sizes according to the size of design 0.25u hang test file to run after the logic is no problem, but in accordance with the method of logic optimization efforts of Labelle's book about the optimization, plus two buffer in the input stage, only the longest path branch size optimization) Platform: |
