Bus Analyzer CompactPCI bus analyzer for use with HP logic analyzers. Form Factor: 3U Part Number: OSS-CPCI-3U-BA-HP Product Features CompactPCI bus analyzer for use with HP logic analyzers 32 or 64-bit CompactPCI bus monitoring Complete State Analysis to 110 MHz, accurate timing analysis to 500 MHz Logic Analyzer Configuration Software CompactPCI bus transaction inverse assembyly software Extension cables ordered seperately

The CompactPCI analysis probe and extender card provides three functions:

1. Acts as an extender for a CompactPCI module beyond the backplane, and provides acess to both sides for easy debug.

2. Provides an electrical and mechanical interface to Hewlett-Packard logic analyzers for passive CompactPCI bus monitoring.

3. Provides test points to measure the power and signal fidelity of the CompactPCI bus.

NOTE: Electrically, the CompactPCI bus is extended approximately 10.0 inches in etch length. Depending on the design of the system, users may experience difficulties with this extension of the CompactPCI bus. The passive logic analyzer termination presents a single electrical load on the CompactPCI bus via low capacitance (10 pf), high impendance terminators, and also provides a matched impedance to the logic analyzer. The analysis probe includes seven, 40-pin logic analyzer connectors. High speed Schottky clamping diodes connected to the CompactPCI bus signals and physically mounted near the extender connector prevent the added etch length from causing unwanted reflections back onto the bus.

The CompactPCI inverse assembly software executes in the HP logic analyzer. In State Analysis mode, the analyzer master clock is the CompactPCI clock. The bus disassembler software decodes the key CompactPCI bus signals and presents a readable display that lists the transaction type, address, data and key status conditions such as wait states and retries. The software also supports user-defined symbols that can be easily added to the state listing display. The user can also select post-processing filters which allow the acquired data to display only chosen transactions. To assist with triggering, pre-defined resource terms have been included that can be used to prevent WAIT and IDLE states form being acquired, thus saving trace memory and providing an easier-to-read state display. FuturePlus Systems also provides a CompactPCI bus triggering application note to all its CompactPCI analysis probe customers.

The CompactPCI analysis probe connects to all the relevant PCI bus signals. Four pods are needed for 32 bit state analysis and six pods are needed for 64 bit state analysis. An additional pod is needed if the user wishes to observe arbitration signals.
