  9. My DaVinci Board

  10. Block Diagram of My Board

  11. 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

  12. Thank You!
