BIST Introduction

The purpose of the offline BIST system is to detect errors and locate the failed module.
The BIST tests are organized in a sequence, and tests module by module. The CPU
executes the BISTs and sends the BIST reply to the operator station.
Temperature, voltage, communication and firmware versions of each board and module
are tested.
