Gentili utenti

Non riesco a capire questo testo, mi aiutereste a trovare una soluzione? "The spacing adjacent to traces listed in this table is a minimum value.
Additional space to other traces can be added and not count as a failure."

Argomento: memorie DIMM DDR2

Contesto:
Options for routing on boards with 4-mil dielectric and on boards with 4.5-mil dielectric are
mutually exclusive. Do not use a combination of these checklist items.

Notes: The four unbuffered DIMM layout rules apply to BTX and non-BTX designs.

The spacing adjacent to traces listed in this table is a minimum value.
Additional space to other traces can be added and not count as a failure.

A two-DIMM design can also be implemented using the four-DIMM design
guidelines.

Layout

General Rules The DIMM placement should be interleaved (DIMM_A0, DIMM_B0,
DIMM_A1, DIMM_B1).

Explanation

Channel B should be routed on the top signal layer in the bus channel
segments.

Channel A should be routed on the bottom signal layer in the bus
channel segments.

The part of the DDR net that is routed with a narrow trace to break out
of the processor pin field should be shorter than 500 mils.

The traces in the DIMM channel are routed with 6-mil spacing to
other traces but can be routed with as little as 5-mil spacing for a total
of 100 mils of length.

All DDR nets in the processor breakout area and the DIMM channel
are at a minimum 4 mils wide.

All DDR nets in the processor breakout area should maintain at least
6-mil spacing to other nets in the breakout region. If three traces are
routed between two vias, the trace spacing can briefly reduce to
4 mils.

In the processor breakout area, the memory CLK and DQS trace
differential spacing is no more than 6 mils.
