17 years agoYes its compiles, but it there is memory waste. i get the same warnings.
if you compile a cyclone II fir for a cyclone III then i would expect that the amount of memory would be the same, and the numer of memory blocks would be less due to M9K instead of M4K. but the number of memory blocks used is the same. for each M4K a M9K is used. so if your cyclone II design uses 36 M4K blocks then it will use 36 M9K. so i copied the fir stuff to the cyclone III project folder and run the wizzard again, only changing the target. and ... now the same design uses less memory blocks. it is clear that the amount will not be half as it depends on the fir. but if both versions produce correct results ... the pcb with a cyclone III is currently in the fab so i have to wait until i can test that, and meanwhile ... quartus 8 is on its way ...
