10M08SCE144C8G Temperature Issues

Hi, We're having some wird temperature issues with some newer 10M08SCE144C8G FPGA chips date marked with "2301A". The FPGA chips are used in an older MUX design "which have always worked before". ...

Hi,
seeing the problem with several boards suggests a systematic effect, e.g. a design timing failure. The reason why it reveals with newer chips can be that they are faster due to technology improvements. Raising temperature reduces chip speed.

First steps would be to characterize observed function failure in detail and to have an expert reviewing the original design for possible timing constraint vacancies and other trap doors.

Yes, your assumtion is probably the correct one.

We have already reached out to an expert which will review the original design and simulate its timing constraints.
