Arria 10 Variable Precision DSP Blocks Floating Point Exception Handling

Hi, Arria 10 documents seem not to specify behaviour of DSP Blocks in floating point modes with infinity or NaN input. In contrast, Stratix 10 DSP exception behaviour is specified in detail in "Vari...

Hi,
thanks for answering. I was specifically asking for propagation of NaN and +/-inf input to Arria FP DSP blocks. It's a valid assumption that hardware DSP implements the same behaviour as FP software IP, but in my view it's still a guess. The behaviour is clearly specified in respective DSP block user manual for other devices like Stratix 10, so why not for Arria 10?

I presume Intel support has more substantial sources to answer the question than conclusions.
