    You cannot create an ADC in VHDL. VHDL describes digital logic, and an ADC requires analogue circuitry external to the FPGA.

    Do you mean you're writing a controller for the ADC?

    there is built in audio codec WM8731 in DE2_115, which takes analog input and convert the signal( sound may be) into digital and

    present the data at ADC_DAT lines of WM8731, so i just want to write its code in vhdl..while its avialable in verilog..but i have worked on

    vhdl thats why i want to develop its code in vhdl.. thanks.
