'''Standard Test Data Format''' ('''STDF''') is a proprietary [[file format]] for [[semiconductor]] test information originally developed by [[Teradyne]], but it is now a [[de facto standard]] widely used throughout the semiconductor industry. It is a commonly used format produced by [[automatic test equipment]] (ATE) platforms from companies such as [[Cohu]], [[Roos Instruments]], [[Teradyne]], [[Advantest]], and others.

STDF <ref>{{Cite web|url=https://yieldwerx.com/tag/stdf/|title=yieldWerx STDF|website=yieldwerx.com}}</ref> is a [[binary file|binary]] format, but can be converted either to an [[ASCII]] format known as ATDF or to a tab delimited text file. Decoding the STDF variable length binary field data format to extract ASCII text is non-trivial as it involves a detailed comprehension of the STDF specification, the current (2007) version 4 specification being over 100 pages in length. Software tools exist for processing STDF generated files and performing [[statistical analysis]] on a population of [[device under test|tested devices]].
