FPGA Central

Hi ..

'm having ADC chip "ADS 8364" wit 25m Hz input Clock . ADC output
Signal Going to FPGA and its out signal going to processor fr further
process.

my problem is before writing vhdl Code i want generate timings ADC to
FPGA but

(1) i don no what is this timing generation ?

(2) why this necessary before Code ?

(3)Can any one give example timing code generation for ADC's

Waiting for all yur Inputs

A timing diagram. Refer to the data sheet for the part.

It isn't.

thanks fr Input

ya i had this Data sheet .. But i want Know how to make use use of Giving
timing diagrams in VHDL Code ..
Can any one Give Give Xmple Code fr Timing Generating Code ..

for what purpose we want generate this Code?

You generate timed sequences of events by writing a finite state
machine clocked by a system clock of known frequency.

We also don't know.
I find it really hard from your post to understand what it is that you
need.
Maybe you are talking about a testbench that when run in a simulator
creates
the waveforms that you see in the data sheet so that you can see
whether your
hdl code reacts correctly to them?

In this case you can do stuff like this:
wait for 10ns;
cs <= '1';
wait for 5ms;
.....
