First, in two layer board, I've heard that people said, the ground trace should be made to the power ground point even when the ground copper is poured on these two layer, could anybody tell me why?
Then, if I use four layer(internal layers are power plane and ground plane), is it true that I don't have to make any power or ground trace on the signal layer, and just use via to the perspective internal layer whenever the power or ground is needed. This is very easy to do and require much less skill to route when it compares to the two layer board. And the cost of four layer board is pretty much the same as two layer one.I don't see any reason to use two layer board instead of four one.
Considering the separation of analog circuit and digital circuit. What I do is using a solid ground plane for digital signal, and making ground trace and mini-partitioned ground on the signal layer for the every analog circuit, and connect these analog circuit ground at the power ground point with star topology. can anybody provide my some advice of my strategy?
I'm designing motor driver and controller, which includes microchip(a lot of digital signal), and motor driver (big current and sometimes high frequency because of commutation), is there any book or documentation that you can recommend to me? I'm really appreciated.
