Hello everyone,
Recently I tried to use Decimation FIR from Advanced Blockset. It worked fine during the simulation until I put the Device block in the design to generate a device specific hardware. When I set device type to Cyclone IV FIR always outputs zeroes. Then I changed device to Stratix II and it worked fine again, same thing with Arria.
So, for some devices it generates working design(Stratix II,Arria) and for some not (Cyclone III,Cyclone IV).
I tried different operating frequencies in Control Block, but it didn't alter the simulation results.
I also tried the same experiment with Single Rate FIR, it also outputs different impulse responces depending on device type!
Does anyone know what can be the reason to that behavior?
Thanks in advance.
