When I wave my hands over it just right, it does. But for a few days
I found it writing jtr/jtr/jtr.ace files in the most surprising
places, including in jtr/jtr/jtr/jtr/jtr/jtr.ace, $HOME/jtr/jtr/jtr.ace,
$(CWD)/jtr/jtr/jtr.ace, and a few other places I haven't thought of.
I'm still occasionally finding jtr.ace files here and there.

And then there's that.

I'll agree that the interface is not particularly intuitive, but the 
main limitation I see is that the ace files must always be placed two 
directories deep. I've used Impact from ISE7.1 on Linux regularly, and 
had no problems at all. I haven't used the 8.1 version much, but a quick 
test seems to indicate that it works the same.

Arrgg... I just noticed that the ipf project files have switched from 
plain text in version 7.1 to binary in version 8.1.

Hey Xilinx, please take a poll of your paying customers. We don't want 
binary project files!

What I would really like something that can write Xilinx .ACE files.
The impact from Foundation 6.2 is terribly slow, and from Webpack8.1
is pretty flakey. (It wrote ace files everywhere but where I wanted
them.)

My latest experience is that it works in Linux, but only if you
start impact in Windows first to initialize the firmware in the
programming cable. If I don't boot Windows first, impact in Linux wants
to upgrade the CPLD configuration which according to other
posts on this newsgroup will break the programming cable.

To be honest, at this point I prefer to use XC3SProg
http://www.rogerstech.force9.co.uk/xc3sprog/index.html
in Linux. Sure, it is rather slow since it uses the parallel cable IV
in cable III mode, but it feels much more stable in Linux than impact does.

is Diligent USB-JTAG cable compatible  with Impact? or it is necessary 
to use another software?

weird I am using PCI LPT ports with base addess typically set to 0xD800

and both impact and chipscope recognize it properly as LPT1 without
any need to specify it manually

Antti 

Hi Marco
I had the same problem. I bought one of these http://tinyurl.com/86sc5
Then had to

set XIL_IMPACT_ENV_LPT_BASE_ADDRESS=xxx

Typically, "xxx" is "378,"  Use the Windows Device Manager to confirm
the base address assigned to LPT1.

Impact & chipscope both worked ok after that.

If you are programming through the JTAG interface, you could try the 
Diligent USB-JTAG cable, which is under $40.

Users of Amontec Chameleon POD ( generic JTAG interface dongle ) buy 
Quatech SPP-100 PCMCIA for resolving this. You may remap any parallel 
port address to the SPP-100.
Work just nice !

Let me know if you do not find Quatech reseller. We have a large stock 
of SPP-100!

( Or buy a new Xilinx USB cables! )

Best regards,
