Re: AD1981B in VHDL

I don't know ur AD specification!! but AD control is not too complex.
you need to write a reference counter and by using this counter you can generate AD_CE (active low) pin , AD clock pin.
if u get AD_DATA from AD chip by serial interface, you should need AD_Serial_CLOCK pin according to baud rate otherwise no need for parallel data.
