Compatibility of compiled design.

Hi, I want to know if it is possible and save to use a Design compiled for a FPGA with commercial Temperature-Range and lower Speed-Grade in a FPGA with industrial Temperature-Range and lower S...

As far as I know, the only differences between the parts are that the I parts passed stricter quality control. They all come from the same wafers.

the C parts will have worse timing specs, so something that passes on a C part should be fine on an I part.

Compilation result is different between a commercial and an industrial Temperature-Range (same Speed-Grade).

I had compiled the same design for an EP4CGX50CF23c7 and an EP4CGX50CF23i7.

The design compiled for the c part work fine on the i part.

But for the same design compiled for the i part, our application showed issues running on target (i part) !!

How can you explain this difference ?

Thanks
