Relative comparison between Cyclone iii , Stratix iii and Stratix iv

hi ashish,

that's a pretty broad question. cost is probably the first thing to look at when comparing cyclone to stratix. ;)

there are probably differences in every category. differences in dsp. differences in luts. differences in high speed io. differences in block memory...

in some applications (and implementation styles) you can port seamlessly from one architecture to another. in others you might have to make some significant changes.
