5.11.8.2.1.6.1 CK and ADDR_CTRL Routing Specification

Skew within the CK and ADDR_CTRL net classes directly reduces setup and hold margin and, thus, this skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces up to the length of the longest net in the net class and its associated clock. A metric to establish this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the length between the points when connecting them only with horizontal or vertical segments. A reasonable trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address Control Longest Manhattan distance.

Given the clock and address pin locations on the device and the DDR3 memories, the maximum possible Manhattan distance can be determined given the placement. Figure 5-76 shows this distance for two loads. It is from this distance that the specifications on the lengths of the transmission lines for the address bus are determined. CACLM is determined similarly for other address bus configurations; that is, it is based on the longest net of the CK and ADDR_CTRL net class. For CK and ADDR_CTRL routing, these specifications are contained in Table 5-57.

A. It is very likely that the longest CK and ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the DDR3 memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net class that satisfies this criteria and use as the baseline for CK and ADDR_CTRL skew matching and length control.

The length of shorter CK and ADDR_CTRL stubs as well as the length of the terminator stub are not included in this length calculation. Nonincluded lengths are grayed out in the figure.

Assuming A8 is the longest, CACLM = CACLMY + CACLMX + 300 mils.
The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8.

  1. CK represents the clock net class, and ADDR_CTRL represents the address and control signal net class.
  2. The use of vias should be minimized.
  3. Additional bypass capacitors are required when using the VDDS_DDR plane as the reference plane to allow the return current to jump between the VDDS_DDR plane and the ground plane when the net class switches layers at a via.
  4. Mirrored configuration (one DDR3 device on top of the board and one DDR3 device on the bottom).
  5. Nonmirrored configuration (all DDR3 memories on same side of PCB).
  6. While this length can be increased for convenience, its length should be minimized.
  7. ADDR_CTRL net class only (not CK net class). Minimizing this skew is recommended, but not required.
  8. CK net class only.
  9. CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes + 300 mils. For definition, see Section 5.11.8.2.1.6.1 and Figure 5-76.
  10. Center-to-center spacing is allowed to fall to minimum (w) for up to 1250 mils of routed length.
  11. Signals from one DQ net class should be considered other DDR3 traces to another DQ net class.
  12. CK spacing set to ensure proper differential impedance. Differential impedance should be Zo x 2, where Zo is the single-ended impedance defined in Table 5-51.
  13. Source termination (series resistor at driver) is specifically not allowed.
  14. Termination values should be uniform across the net class.
