I used different version of Quartus to generate same core (ALTMULT_ADD). I noticed there are a few differences on the generated .VHD file, one of them is : 

PRIVATE: RNFORMAT STRING "33" vs PRIVATE: RNFORMAT STRING "16" 

 

tried to search what RNFORMAT is, but can't anything. Any know what RNFORMAT is?  

 

Why the core generated by older version of Quartus has different number of string value from the the core that is generated by the newer version of the Quartus \? 

 

Thanks!!!

No idea. Stuff like this is probably to do with internal stuff. And different versions of quartus support different things, hence the different results.
