A comprehensive analyzer for the JIAWG high speed data bus

The author explains the HSDB (high speed data bus) protocol, describes the HSDB-A (high-speed data bus analyzer) hardware, and presents HSDB-A operation from the user´s point of view. The HSDB provides 50 Mb/s maximum bandwidth, adequate throughput, and excellent fault recovery characteristics. The HSDB serves as a mission avionics bus, coordinating processes among integrated racks. To debug systems interconnected by the HSDB, engineers need a comprehensive support tool that can monitor the bus, maintain bus performance statistics, selectively capture bus traffic on error or trigger conditions, emulate nonexistent terminals, and stress the bus to the specification limits. The HSDB-A fulfils this need
