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
