I coded a driver for AD5791 in verilog and SDIN, SCLK, SYNC, LDAC, RESET and CLEAR is correct in Modelsim. Also I get the right waveform in oscilloscope after downloading in FPGA. But still, the Vout do not follow my code.

VREFP = 5V

VREFN = -5V

VDD = 12V

VSS = -12V

VCC = IOVCC

I delay 5s to write control register with 24'h200012,and DAC register 24'h33333, but still Vout is 0V.
