specctra sdram pcb
Hi Guys
I am new to PCB design. Can any one pls tell me how to equalise net lenght. I have a fpga and a Microcontroller on the pcb and need to route the address and data bus. the pcb is a 4 layer and i am trying to route data on top layer and add on bottom layer.
Due to pin layout of the buffer for add and data bus, nets having different lenghts....
thus can any one pls tell me how to equalise them. i read at many places that try to route them in a zigzag manner. At the same i also read that routing of data and address bus should be parallel, i mean all the add and data lines should be parallel to each other... this is contraditory to what is said in equalise net lenghts...
guys pls help me understand this more clearly...
thanks in advance
