> I think it's more that the compile was unconstrained, so no floorplanning or handholding synthesis anything i mean they don't say anything about how long they let it run for - constraints are to narrow the search space for human-time-scale benefit right? i'm sure if i let vivado run (i'm not an intel person) until heat death of the universe it would also give me some fantastic fmax numbers too. > Too bad they don't seem to have released their code, though. and they never will. i don't know what it is about this kind of research (or how you can even get away with this) but it's almost unheard of for the commercial groups to release their code/rtl/tcl scripts. i have emailed around before and i just continually get shined on - "oh we're planning to release but it has to go through legal". and this is from my capacity as a phd student ie not direct competitor. and it's funny to me because if you're selling these boards/part/fpgas aren't you strongly incenvitized to throw as much sample code over the fence as possible so that people buy your hardware in order to use your code?
