Abstract

Before becoming fully operational, a FASTBUS system must be initialized; each segment interconnect (SI) must be downloaded with the correct route table, group address (GP) assignments must be made to each segment, etc. Furthermore, each system component must be initialized in the correct order; a given segment cannot be accessed until all SIs on the path to that segment have been initialized. It is desirable that the initialization procedure be automatic (i.e., requires no. human intervention), be driven from a database containing the system topology and information of all devices in the system, and assure that the system is placed in a completely specified state regardless of the initial state. This paper presents an algorithm for doing this whicn nas been successfully implemented at the Fermilab Collider Detector Facility (CDF).
