If an RPD file contains only configuration data, why does Quartus generate differing RPD files for EPCQ and EPCQA devices? Shouldn't they be identical?

Hi Vikas,

Thanks for the quick response. This gives me some things to try.

But maybe you can help a bit - my design is initially configured using the Altera Blaster. The technician loads the correct JIC file based on which device (EPCQ128 or EPCQ128A) is on board. All is good.

But, for remote field update, I was hoping to have an RPD (or other type) of file that would work for either of the 2 config ROM types.

Can I just create the RPD using the variation that has the most dummy clocks and expect it to work for both?

Thanks and regards.

Mark
