Hi Andreas,

Thanks for your feedback, I cant understand why this is not working with 
ISE? I have ISE 9.2.03i for Win32, really strange that I cant choose
the Virtex2 board xc2v6000?

Anyone an idea whats wrong?

Cheers!

I was explicitly told by EDK 9.2 that it no longer supports Spartan-II, 
Virtex, Virtex-E, Virtex-II, or Virtex-II Pro devices. ISE 9.2 may be 
the same.

As a result I'm sticking with EDK 9.1 for the forseeable future, since 
the board I've got is the Xilinx University Program Virtex-II Pro board.

So the question is, if I am able to get a copy of ISE 9.1 ...
have to check the xilinx homepage...

Dear Philip,

on the web site xilinx claims that edk9.2i is also support virtex2 and
the other mentioned older xilinx devices. So the message in the bsb
dialog is not conform to the contens of the xilinx web.

Dear Harald,

in the mean time i have made a test design for xc2v6000 on a windows
ise92.03i installation without any problems.

Perhaps you have not installed the full ise or the service packs ?

The devices on the PCI bus, for example, are memory mapped and eat up
quite a lot of address space. There are ways to use the RAM between 3
and 4 GB, but you're on the safer side if you put 3 GB in your machine
if you can live with that. Otherwise think about using an 64-bit OS.

Xilinx has a web page that gives some details about the memory
requirements of ISE depending on the target device.

The wizard generates 2 files, the top file and the user logic file. Make

Thanks for your effort Andreas, I just updated the tool yesterday so 
this seems pretty strange. As I said, I have the same version as you, 
really weird that I cant find the Virtex2-XC2V6000 board in my options?

Have to check this further!

Dear Harald,

i think you are currently using the ise webpack edition. the webpack is
limited to the from you reported devices

see also the list http://www.xilinx.com/ise/products/webpack_config.htm

the ise 9.2.03i that i use is a full version, not a webpack edition

Andreas

I am quite sure I can reproduce the entire chain of hoops
in xapp058. It would allow me to eventually reverse engineer
their jedec -> jtag mapping in a matter of days or may be
weeks if I want to include more devices.
 The "impact" tool Antonio is using is not available on the
xilinx website, but I am sure I could find it as well, it
must be out there.
 Yet the question remains - _why_ do they keep the mapping
data secret? I predicted we may wait for a century or so
for a plausible answer - the first one we got from their
CPLD support is more arrogant than it is ridiculous. Who
does this person think is talking to, housewifes? Their
JTAG interface is too complex for us to handle, yeah,
in fact some of us have handled the coolrunner jtag interface
before xilinx had a clue what the coolrunner was.
 I wonder if this reply is more arrogant and rude than
the one I got from their "support" department 5-6 years
ago, then they wanted me to make the $20M/quarter revenue
before they would consider talking to me. I'll dig that
message and post it here as well, this is the least their
arrogance deserves.

My mistake, it has been $9M, not $20M.

Mrs. Hughes,

thank you for your reply - it answers my questions to a great extent.
What I still do not understand is:

>Our Major Accounts only have access to this information

>ii) If they specifically ask for this information.

Do only those comapnies get the information who cover both i) and
ii) ?

Does that mean that they all get access to the information only after
they have made the first $9M/quarter for you, wether they have asked
for this information before this or not?

Mr. Popoff,

I'm glad I managed to answer part of your question. In answer to
the question below:


> Does that mean that they all get access to the information only after
> they have made the first $9M/quarter for you, wether they have asked
> for this information before this or not?
>

They will not get automatic access to this information, they must
first have made the $9M/quarter and then they must ask for it.
Some customers may generate more than $9M/quarter,
but if they do not ask for the information, they will not get it!

I hope this resolves your query fully.

Regards,
Caroline Hughes.

=======================================================================

Now we have them worried about our JTAG chain wellbeing.

 They are so hostile about these issues it is obviosly
not just about the data being kept secret, there is
more to it than that. I wish I knew what...

Hi Dimiter,

Could you elaborate why you can't use other low power CPLD's, Lattice
4000Z, for example? I'm asking this question because in Lattice case
there is C code supplied for you to make the kind of CPLD programming
discussed in this thread very easy.

This tells you  the U is driven onto data_in by your "uut" component.
Therefore Duane's advice applies.

Why does your memory need to drive its Data_In bus?

If it doesn't; simply make Data_in an IN port.
If it does, make the UUT itself ... not the testbench... drive Data_In
with 'Z' as Duane suggested, to replace the "U"...

Either of these should solve the problem.
Having changed the design, use the Drivers command again to verify the
change.

hi

thanks for all your advices! i found the problem.
somehow the signals in the component instantiation got messd up
(although i used the testbench generated by ise).
anyway the problem was that data_in, data_out and RD, WR, CLK where in
the wrong order. the only thing im wondering is,
shouldn't ise or modelsim throw a warning?

Hi

We are thinking of buying a Xilinx Virtex5 evaluation board. At the 
moment this one seems to be our favorite:

http://www.xilinx.com/products/devkits/HW-V5-ML505-UNI-G.htm

Price is 1195$, which is quite reasonable. Are there perhaps other good 
products with a Virtex5 on it out there, perhaps some that have special 
prices for universities?

Thanks P.

Luc,

I understand your decision.  And, I hope all goes well with your project.

I will say that after what happened during the introduction of V4 FX,
that Xilinx has placed many "gates" and "systems" to prevent a
re-occurrence of that terrible time.

To that end, the release of Virtex 5, and the GTP's, has been a real
pleasure (for us, and our customers).

I cannot - have not checked them recently, will do and will
report :-).

Philipp,

Are you a university or school?  If so, you should contact the XUP
(Xilinx University Program).  We often grant (gift), or partially fund
university boards (like the Virtex II Pro board from Digilent that we
will provide the FPGA on -- the school only pays for the pcb, not the FPGA).

Otherwise (not a university), our distributors also have an array of
Virtex 5 pcbs for sale, too.

http://www.xilinx.com/onlinestore/v5_boards.htm
(don't miss the HiTech Global, and TED/Inrevium links, at the bottom left).

Subject: Xilinx Virtex 5 ISERDES vs ISERDES_NODELAY: which is better for DDR?
From: Barry <barry374@gmail.com>
Date: Tue, 20 Nov 2007 07:50:58 -0800 (PST)
Links: << >>  << T >>  << A >>
The Virtex 5 Library has two design elements for the ISERDES.  The
ISERDES_NODELAY obviously does not include the delay element, but it
has another difference.  It has a secondary clock input (CLKB) that is
not included in the ISERDES.  CLKB is supposed to receive the inverted
CLK for DDR mode.

So I don't understand the difference - why doesn't ISERDES also have
the CLKB input, and which is better to use for DDR mode?

TIA,
Barry

Thanks for your answer Austin, yes I am at university. So I will check 
with the Xilinx University program. Unfortunately it seems that the 
board you are offering is too small for my purposes. I would need
a evaluation board with at least a Virtex4 on it and around 25000
to 30.000 slices.

If anyone knows a good resource where I could get such a board I would
be thankful for some feedback ;)

Cheers,
Philipp

Have a look at Broaddown4 http://www.enterpoint.co.uk/moelbryn/broaddown4.html.
An alternative solution is the combination of our Broaddown2
(Spartan-3) with a add on Swinyard1 module. The Broaddown4 can support
between 1-4(with 2 Swinyard1 modules) Virtex-4 LX40-160 or SX55 parts.
Swinyard1 has a single Virtex-4 LX40-160 or SX55.

Some outline details on our university program (UAP) is here
http://www.enterpoint.co.uk/uap/uap.html. Discounts are listed there
on some products, others are available, as are details of our
Synplicity deal for universities where they effectively get a free
license with a small pack of our low cost board Raggedstone1 and soon
hopefully some others.
