DESCRIPTION

Standard Test Data Format (STDF) is a widely used standard file format for semiconductor test information. It is a commonly used format produced by automatic test equipment (ATE) platforms from companies such as LTX-Credence, Roos Instruments, Teradyne, Advantest, and others.

A STDF file is compacted into a binary format according to a well defined specification originally designed by Teradyne. The record layouts, field definitions, and sizes are all described within the specification. Over the years, parser tools have been developed to decode this binary format in several scripting languages, but as of yet nothing has been released to CPAN for Perl.

Parse::STDF is a first attempt. It is an object oriented module containing methods which invoke APIs of an underlying C library called libstdf (see http://freestdf.sourceforge.net/). libstdf performs the grunt work of reading and parsing binary data into STDF records represented as C-structs. These structs are in turn referenced as Perl objects.
