Signal Naming Conventions
Refer to Figure 26-1 on this page, Figure 26-2 on page 685, and Figure 26-3 on page 685. The specification uses the following documentation convention in signal names:
“w” in a signal name is replaced by:
- “p” for the positive rail of a differential pair.
- “n” for the negative rail of a differential pair.
“x” in a signal name is replaced by the port number.
- Can range from 0 to n–1, where n is number of connectors/ports on the board edge or the backplane.
“s” in the signal name:
- On a board, “s” is replaced by:
- “t” for an IO plate connector or
- “b” for a backplane connection.
- On a backplane, “s” is replaced by the slot number.
“I” = input signal and “O” = output signal.
