[SOLVED] Why we need Wgl file format

[shalin mandiwala]

Hello All,

My Question is Why We need WGL(Waveform Generation Language) File format when we have STIL file?
We already have STIL file for pattern information then why we need WGL file?



Thanks in advance.

I have only worked with STIL patterns, had never generated WGL. Even then we had to convert STIL to a proprietary pattern so that they could be fed into Advantest.
Whavever little I know and making an educated guess, the reason might be for operatability with various tools/scripts/software.

As far as I know, WGL format is mainly required because of the specific tester requirement.

Thanks maulin,

Can you give any example in which specific tester environment we need to use WGL?

If you are talking about ATE testers, machines which are used for post production tests, then these ATEs have their own formats. WGL or STIL test vectors generated by ATPG tools have to be converted into another format suitable for the target ATE tester.
e.g- Advantage T series testers do not support the STIL or WGL data format.
