1)How to perform the group routing,because my PCB work contains so many buses,I want to route these buses as same length as possible.
2)My PCB contains many differential lines,how to route these differential lines in the same length? I kown that there is a setting in PowerPCB to set the differential line,but how to perform the route?
3)My PCB contains a RAMBUS,as we know that RAMBUS is sensitive to the impedence,how to calculate the impedence?i.e how to perform high speed design in PowerPCB?(There are may high frequency clocks in my board)
Thanks to any freinds who can kindly help me!!!
