Read output from external chip using microblaze

Hi all
I got stuck with my design. I'm planning to use microblaze in ML505 board
to read my full custom chip output and display to hyperterminal.
I've found one tutorial about read DIP switch using microblaze, but here I
want the output of my external chip to be read by microblaze.
I'm confused of the device_ID that I should use in my programming so that
the microbalze can read the signal.

FYI, I want to test my chip by driven the input signal using test vector
that I've designed using VHDL in Virtex-5(ML505)and the test vector output
will be the input of my chip. Then my chip will produce the output and
display at hyperterminal using microblaze.

Hope somebody can help me with this.
Thanks

ChipscopePro does that, I think. I mean, I know what chipscope does; just
not sure if you meant what I thought you were trying to say. There's a 30
day free eval license.

The microblaze needs the embedded tools edition. That's dandy if you have it
already. (In which case, you already have ChipscopePro.) Eval license for
that is also available.

I wouldn't take the microblaze approach, to solve apparently a small problem
with a much larger project. I'm assuming here that if the data rate is slow
enough to make a serial terminal feasible, it's a tiny tiny problem.

Gpio interface is the answer to your dipswitch question. Anything much more
complex really would be better on chipscope.

What is the interface of the "full custon chip" that you want to read?
Or is it just a bunch of signals?

Hi
my interface is a test vector generator(vhdl file) to generate the 2 input
of 8-bit to my full custom chip. output of my chip will be read again and
compare with expected result and also to display at hyperterminal.
Actually i want to make this simple, but this is the only plan I have to
display the output by using microblaze.
Do you have any idea to solve my prob?Thanks.

Does the phrase "sledgehammer to crack a nut" mean anything to you?
Unless you are allergic to HDLs, it is time to learn digital design and
Verilog or VHDL.
