Hello,

I am new to FPGA debugging using ChipScope.

I know that ChipScope Pro tool is an internal logic analyser for FPGA
Hardware designs....

But, is there a way to debug a hardware design that is not made on FPGA,
using FPGA's ChipScope tool?

Thanks for your help!

Roger

Chipscope is only for debugging Xilinx FPGAs.

If you create a design on a Xilinx FPGA where the signals wired to the
ChipScope are fed by external signals and add some trigger logic and
clocks I don't see what can stop you. Maybe just the availability of
better and cheaper dedicated solutions.

It's easy to do if you have a FPGA of a board that has lots of I/O
free and accessable. A number of our customers use our Darnaw1 FPGA
module http://www.enterpoint.co.uk/moelbryn/darnaw1.html to do just
than because it has a large I/O count. Basically this module is turned
into logic analyser head with a simple design with inputs fed to a
Chipscope core. When doing this it is important to use I/O registers
to avoid timing skew and distortion.

Accuracy is related to the sample clock that you use. Usually the
onboard oscillator of the Darnaw1 is multiplied up by a DCM within the
Spartan-3E FPGA to get something like a 100-200 MHz sample clock.

The remaining problem is the flying wires or if planned a socket on
your board. For flying wires keep these of equal length and if
possible use a screened cable.
