Gate level Simulation passes but design fails on target borad

Hello, I am implementing a filter (2nd order) in Quartus Stratix II device running at 500KHz. I simulated the design using ModelSim. My Target hardware consists of stratix II device. Input...

I am sorry, i did not get ur point.

I see attenuation in gate level simulation for various amplitudes and various cut-off freq's.

If Amp = A, then output = 10% (A), as desired at cut-off freq.

Is this not Okay & sufficient to say filter works at gate level?

For coefficients calc: float * 2^30 = decimal value, converting this to hex will give my coefficients as mentioned.

Kindly suggest..
