However the STDF version 3 don't have a public available specification (If at all the version 3 spec is unique for all companies). The parser will support both STDF version 3 and STDF version 4. And I also build an automated yield extraction and reporting tool based on this parser which have now totally substituted the old tool we were using. Thus I developed this brand new STDF parser that supports both STDFv3 and STDFv4. However somehow (possibly due to the limitation of my knowledge) I found pystdf is a bit diffcult to understand and not easy to extend to meet my personal requirements.
Another project pystdf is already there for sometime which supports STDF v4 very well. This, for me is troublesome and lack of the possibility to fully automate data processing and extraction. The old solution is to convertion it to another format (such as TSF) and then open such files with another dedicated tool. STDF ResourcesSTDF on Wikipedia STDF Group MotivationIt could be very useful and convinient to directly look into STDF files, and enables more complicated test data analysis framework to be based on this parser. It is the file format most likely being created at production line due to its compactness to save storage spaces. What is STDF?STDF is the standard test data format used by many of the ATE vendors such as Teradyne.
