Parser for (Altera) FPGA programming files

[tv84]

I've created a small parsing utility that shows the contents of some Altera (+ others??) .SOF/.POF/.RBF/.JIC/.RPD files.

It's a very rudimentary experimental tool but it can show some of the contents of theses files (CRCs, checksums, etc...)

Sometimes it can help people understand why their files fail programming, etc.

There's little information available on this (proprietary) topic so if you have anything to add or correct, or find a file that doesn't process, please leave a msg.

Hello  , I'm currently working on bitstream parsing. I was wondering if Altera has publicly available documentation on the configuration file structure. Could you please explain how your tool is developed?

The detailed format of an Altera FPGA configuration file is non-public proprietary info. You would need to sign an NDA to get it.

The higher level format of some files (like .POF for example which originally came from DataIO the programmer maker) are available.
Likely that info is what was used to develop the original parser application. But it won't tell you how the individual records are encoded.

Ummm....

can you provide source code?
