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.
