摘要
提升处理器核的频率是提升处理器性能的重要手段.传统的物理设计流程难以实现高主频的处理器核.基于业界主流的布局布线工具,通过嵌入手工定制部件的网表、逻辑和物理设计协同优化、优化定制布线规则、优化物理设计方法学等组合策略.在相同工艺、面积、功耗对等条件下,达到流片签核要求时,自研处理器核物理设计频率比原始设计可提升约30%.
Promoting core’s frequency is the key method for increasing performance of processor.It is hard to achieve high frequency for processor core by traditional physical design flow.Based on main place and route tools,with the same process,comparable implementation area and power consumption,our own processor core frequency can be pro-moted by about 30%compared with original design at signoff stage,by employing manually written block netlist,logic and physical design co-optimization,custom routing rule optimization and physical design methodology adjustment.
