Curtiss Wright Controls Defense Solutions’ Vanguard PMC Bus Analyzer offers the complete solution for PCI / PCI-X analysis, exercising, protocol detection, and compliance checking in a PMC environment. With a 10/100 Mbit/s Ethernet interface, the Vanguard PMC takes Curtiss-Wright Controls’ power and flexibility in Bus Analyzers to unprecedented productivity.

Due to size restrictions imposed by the PMC form factor, Curtiss-Wright Controls has uniquely designed a single, fully integrated module for the Vanguard PMC, allowing another PMC module to be carried on top. This fundamental feature allows analysis of the PCI/PCI-X bus without removal of a PMC module. The pass-through of the PMC P4 connector accommodates PMC modules with rear I/O (e.g. to P2ac on VME boards). A PC running Windows and BusView graphical user interface or an Application Programming Interface (API) controls the bus analyzer.

State Analyzer
With highly advanced (yet simple to use) triggering, filtering and counting capabilities, the Vanguard PMC State Analyzer captures and displays 64- or 32-bit PCI-X/PCI bus activity up to 133 MHz. The state analyzer’s choice of three sampling modes--Clock Mode, Transfer Mode and Standard Mode--provides optimum bus analysis for a given problem.

Exercisers
With two flexible and easy to use Exerciser versions (basic and enhanced) Curtiss-Wright Controls’ Vanguard PMC exercisers allow concurrent operation of two DMA engines, a target memory with I/O and memory spaces, and a command executer. The flexible script feature allows users to make test scripts and to automate tasks.

Protocol Checker
The Vanguard PMC’s optional protocol checker for PCI-X and PCI automatically detects up to 71 PCI-X and 45 PCI protocol errors, helping the user to find bus hardware errors without even understanding the problem. While the state analyzer, the bus utilization statistics, or other Vanguard PMC Analyzer functions are active, the protocol checker can run in the background, screening the bus for errors. If the protocol checker is used as the trigger source for the analyzer(s), the state and timing analyzers provide a comprehensive picture of the bus activity around the point when an error was found, helping the user to identify and correct the problem.
