1 Introduction
This document contains a description of the Teledyne LeCroy Verification Script Engine (VSE), a utility in
the PETracer™ software that allows users to perform custom analyses of PCI Express™ (PE) traffic, recorded
using the new generation of PCI Express protocol analyzers.
VSE allows users to ask the PETracer application to send some desired “events” (currently defined as
packets, link transactions or split transactions) from a PE trace to a verification script written using the CATC
script language. This script then evaluates the sequence of events (timing, data or both) in accordance with user-
defined conditions and performs post-processing tasks; such as exporting key information to external text-based
files or sending special Automation/COM notifications to user client applications.
VSE was designed to allow users to easily retrieve information about any field in a PE packet header or
link/split transaction, and to make complex timing calculations between different events in a pre-recorded trace. It
also allows filtering-in or filtering-out of data with dynamically changing filtering conditions, porting of information
to a special output window, saving of data to text files, and sending of data to COM clients connected to a
PETracer application.
