Advices for DaVinci Hardware Development
Be sure your schematic is correct Keep the analog circuit as far away as
can from the digital circuit DDR layout keep different nets far away enough (3w or 4w) All nets in the same net classes have
to be skew matched Don’t cut the ground plane next to
every DDR2 routing layer
