6.10.3. Board Layout

Board layout is more sequential in nature than schematic design. A general sequence is:

  1. Stack Up details - Laminate Selection (Dielectric constant (Dk), weave, losses, etc.), Planes, Impedance and Layout Constraints (length match, within pair skew, pair-to-pair skew, loss, and others.)
  2. Critical nets – anything with special constraints:
    1. EMIF / DDR
    2. HSSI / Transceiver
  3. Other signals
  4. Power
