Verilog code for A/D and D/A converter

[rsk]

Dear Friends,
Can any one had the verilog code for 16 bit A/D and D/A converters i
need them because in my project i need to pass voice signal through A/d
Convertor to get 16 bit digital data and then i have to compress it to 8
bits and it to receiver where i will again decompress it to get 16 bit
digital data then i have to pass it to D/A converter to get voice
signal.


I will be waiting for your reply...

Thank you,

krs...

Yeah, I know these(A/D and D/A PLL's ) are designed by the analog design
engineers and i think for that we need Verilog-a and spice tools but
my friend wanted to do that with verilog or vhdl and he is insisting to
do that with either of those hdls only then i got a doubt do we able to
do that and wanted to verify it, so we wont be able to do that with
HDLS (veriog or vhdl).And i told the same to him.But before ascertaing
him about that i wanted to verify it thats why i posted this message

Any how thank you very much Mike...

Verilog doesn't model analog components. However, if all you
need is a functional model of the entire converter, for testing,
you might be able to write that. Presumably your input is
some kind of data file containing real numbers representing
the input voltages. You should be able to write some behavioral
Verilog code that converts those real numbers to digital values
and applies them to your design. Or write a C program to process
the data file into a data file containing the digital values,
and read that into your Verilog.

Probably the closest you'll get..

Cheers,

Isn't this an analog operation ... or at least don't you need some analog
aspect
to do an A/D or D/A?
