Figure 44: 16-Channel midbus footprint connection module connector
The serial analyzer software is designed to be easily con
fi
gured based on these
standard formats. If your system design does not allow you to follow these
guidelines, or if a footprint is incorrectly wired, you may have to disassemble and
rewire the connector at the module end of the probe. (See page 58,
The differential pairs that make up a PCI Express link must be connected to
speci
fi
c pads (pins) on the footprint
The polarity of the differential pairs can be swapped, if required, for routing
Upstream and downstream channels can be swapped on a footprint, if
required, for routing
Entire links can be reversed compared to the suggested routing
Key concepts for the channel mapping tables.
Each channel is connected to either an upstream or downstream differential
pair.
Signal name = C[
number
][
p
(positive) or
n
(negative)]
Example: C3p = the positive signal of the differential pair connected to
channel three
Channels are grouped together in sets of four in probe-to-module connectors.
