Convert EPM7192EQI160-20 POF file to EPM7192S

[FlipZ]

Hello,

I am maintaining legacy equipment with EPM7192EQI160-20 CPLD's.

In case they go bad we would like to replace them with JTAG-version EPM7192S ones as they are easier to program.

Is there a way to convert the POF files we have to EPM7192S POF files so maybe we can use a USB Blaster to program them?

Regards,

Flip

Download Quartus 13.0sp1 and recompile the source for the EPM7192S device.

Per the datasheet v6.7 from Sep 2005 the 7192E and 7192S are pin compatible (lucky you) but there are differences
in the internal routing architecture in the core of the devices. So you must recompile. There is no POF translator.

There's at least EPM7192S open drain output feature that involves additional bits in the fuse table. Thus binary files can't be identical. If you'd know the fuse table encoding you could probably write a translator. There's a minimal chance that someone at Altera has written such a tool 20 years ago. However it's just a click with MAX2Plus software or a bit of importing with Quartus to generate the new files. It's only a problem if you don't have proper design archives.

Thanks for the feedback. Will see if the source code is still somewhere in the attic here ...
