I am at the point where I need to route the DDR3 Signals of the CPU core. What that means is that I have a bunch of signals that need to be routed to the same length to two different chips on the board. I think the rats nest tells a lot about the thinks to undertake for DDR3 routing. 

KiCad is very limited in the features making the job a little easier. So my next endeavor is to put some features into the KiCad source-code to give an overview of the track length and stuff like that. 

If you can read German you can have a look at my Blog for some detailed information.
