Chapter 7 Troubleshooting Tables
7.1
List of Board and IC Signals
Due to the nature of the schematic-generating program, signal names might be different when they
are not directly connected to the same point. The tables in this chapter provide a cross reference to
the various pinouts for these signals.
Table 7-1
lists and provides links to each of the tables in this
chapter.
