i am in need of simple ADC code in vhdl with analog input at port grater the bit better it will be
can anybody help me ?
 

As far as know there are no Analog Digital Converter (ADC) embedded in the FPGA. You should use external module and the interface for the ADC can be written in Verilog or VHDL.
 
actually i need the code in VHDL for ADC for my xilinx spartan 3E-500 FG 320
plz help
 

Please describe the hardware that u r using. I mean which development board or custom card.

Anyway, the tutorial here implements an oscilloscope, so they are interfacing the ADC. It will help you.

i am in need of ADC code in VHDL i.e. to programe ADC instead of using ADC IC

I suggest you read the data sheet of the ADC and create a controller accordingly.
