FPGA Central

My Spartan 3 FPGA kit came with a cable that's supposed to plug into a
DB25 connector. However, the laptop computer I'm using for the kit
does not have any such jack on it.

What adapter can I use? My laptop has USB ports and a DB9 but no
DB25.

Something like this: <http://sewelldirect.com/DB9toDB25.asp>

30 seconds to find it with a search engine!

What you need is a printer port. A better solution is to buy a Xilinx
platform cable USB and give the parallel cable to someone who can use it.

(someone else pointed you at a db9-db25 adapter, probably for serial,
which is not useful to you)

OK, I ordered the JTAG/USB cable from Digilent.

Oops.

I do have programming pods with db25 serial, but I should have
realized that with anything as new as a spartan3 the db25 would be
parallel, not serial.

Note that Digilent's JTAG/USB cable does not work with the Xilinx Impact
program. You'll have to use Digilent's programming software or find other
software that supports that cable.

That also means that the Digilent cable doesn't support Xilinx Chipscope,
or the EDK debugger.

My understanding is that there's a hack to make it work with impact
via the cable server mechanism in the sourceforge project at

http://sourceforge.net/project/showf...roup_id=175344

however the usb cable related source file is not part of the default
project build, so it's not exactly turn-key.
