LeCroy Corporation Verification Script Engine Manual, version 2.2
1 Introduction
This document contains a description of the LeCroy PSG’s Verification Script Engine (VSE), a new
feature introduced by LeCroy in its UWBTracer™ software that allows users to perform very complicated custom
analyses of Ultra-Wideband (UWB) traffic recorded using the new generation of LeCroy Ultra-Wideband protocol
analyzers.
The VSE allows users to ask the UWBTracer application to send desired “events” (currently only frame
level events are available) that occur in the recorded UWB trace to a special verification script written using
LeCroy 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
files (in text or binary format) or sending special Automation™/COM notifications to client applications.
The VSE fully utilizes the high performance and intelligence of LeCroy PSG’s decoding capabilities,
making processing of information easy and fast. VSE can:
• Retrieve information about any field in UWB frame headers, contents of frame payloads, serial data, and bus
states.
• Make complex timing calculations between different events in pre-recorded traces.
• Filter-in or filter-out data with dynamically changing filtering conditions
• Port information to a special output window
• Save data to text or binary files
• Send data to COM clients connected to the UWBTracer application
