Ramp generation through HSMC DAC Stratix III using DSP Builder

I am able to generate proper ramp signal in DSP Builder simulink but when I program it into the FPGA, the output signal through the HSMC DAC is saturating. What is causing this and how to remove this...

I tried for 10 kHz, the output did look like a ramp but actually that too was saturated. I could not get any solution for this. Using an analog ramp generator circuit is the only solution for now.
