LeCroy Corporation Verification Script Engine Reference Manual Version 1.01
1 Introduction
This document contains a description of the LeCroy Verification Script Engine (VSE), a new
utility in the SATracer/SASTracer software that allows users to perform custom analyses of
SAS/SATA traffic, recorded using the new generation of SAS/SATA protocol analyzers.
VSE allows users to ask the SASTracer/SATracer application to send some desired “events”
(currently defined as Primitive/Frame/Transaction/Command) from a trace to a verification script
written using the 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 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 SAS/SATA
Frame/Transaction/Command, 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 SASTracer/SATracer application.
