No, it's not. I have tried to register with Xilinx support, but I got a
reply that stated that since I was not an employe , but only a student, I
could not get direct support.

May be there is some part of  "You can not join" that I did not understand ?

Well, Mr. Mcgettigan, I hope you will come up with an e-mail  to someone who
can give me som answers about HARDWARE issues on the SP305-board itself .
Thats all I ask for.

It's 4:00 saturday morning here now, so I'm turning in. I have a nice day
ahead of me, no clouds and
80 F +. I have no boat, I'm sorry to say, but I migt take a trip out to one
one the local islands here i Oslofjorden, and just relax.

Have a nice weekend !

PS.
Give me best regards to Austin as well.
DS.

I would highly recommend the *free*, multi-OS Perforce Visual Merge
Tool (P4Merge -- http://www.perforce.com/perforce/products/merge.html)
This is a true three-way merge tool, which is what you want when you
are doing multi-user code development.

You give the tool two or three versions of the code.  Two-way merge is
exactly as with any other tool.  However, it's three way merge where
P4Merge really shines.  You supply the "Base", "Left", and "Right"
files to it.  The Base is the file you started with before making your
changes.  Left is your file.  And Right is the other file someone else
has created -- they've made changes (starting from base) at the same
time as you were making your changes.  It will then do a correct merge,
and it does an excellent job flagging conflicts.

This is the tool many of ourdevelopers use for merging, and in my
experience, it is signficantly better (fewer mistakes, better conflict
identification) than many other tools.

Well, try to change the port.  My Cable IV would not work at all on my

is the case for you ?

Subject: initialization sequence and auto refresh for sdr-sdram
From: "Subhasri krishnan" <subhasri.krishnan@gmail.com>
Date: 10 Jun 2006 05:01:16 -0700
Links: << >>  << T >>  << A >>
Hi all,
I have some basic doubts. The initialization sequence for sdram's from
different chip manufacturers vary slightly although the ones that I
have referred to(micron, samsung, hynix) use "precharge followed by 2
auto-refresh cycles". how does this wake up the device? Also does the 2
cycles here mean two complete refreshes of 4096 rows?

My understanding is this. Once I power-up and initialize using burst
type auto-refresh, my device is in idle state and because I write/read
every row and column more than twice within 64ms,  i dont need any
refresh. Although from post-place and route simulation results I can
verify that the logic and timing for memory controller is ok, the
pattern still looks very strange(on the monitor after configuration
with the bit fle). It looked to me like once every few rows, a wrong
row is opened. The only thing that changed this strange pattern was the
auto-refresh counter in the initialization sequence

Auto-refresh specified can be implemented either as a burst of 4096
cycles every 64ms or can be distributed every 15.625 us right? so while
initializing the device if I use burst type command then after 2
complete cycles the device should be in idle state. Does the internal
refresh counter stop working now? and if I dont issue any refresh then
it cannot carry on any kind of refresh operation now can it?

Any help is greatly appreciated.
Thanks

Hello, both VHDL and Verilog are well established standards that have been 
widely adopted by the engineering community. Excellent behavioral simulators 
are available for both of the languages. Therefore it would be prgamatic to 
use Verilog and VHDL for new projects. AHDL is simple to use but a lot of 
what can be done in AHDL can be accomplished with Verilog and VHDL. As 
language parsing and synthesis are two separate processing steps all three 
languages benefit from the improvements that are made to the Quartus core 
logic synthesis and technology mapping algorithms. Therefore you will be 
able to achieve equivalent Quality of Results with all three languages.

Does anyone here know the purpose of the SDRAM initialization sequence?

I have never implemented it and never noticed any sort of failure in my
designs.

This may be because I mostly use it for frame buffers and fifos
(sequential access), not cpu (random access) designs.

I am not sure I understand what you're saying. You never implemented
the initialization sequence? Isnt it essential to do it irrespecitve of
the way the sdram is used? or maybe you meant auto-refresh? Please do
clarify.

I am also working on frame buffers and noticed that some of the scan
lines looked wrong. Auto-refresh seemed to be the only command that
affected the image.

I have never implemented the SDRAM init sequence.  The manual says it
is essential, but not why.

Also, I don't refresh (auto or otherwise) since I am continually
writing and reading every row that I am interested in.

This has worked fine for me with several different designs and several
different SDRAMs (Hitachi, Micron and Samsung that I am certain of).

It seems that you are trying to do a similar thing, so I don't know
what is causing you problems.  I didn't use refresh (auto or otherwise)
because I didn't need it and it would have interrupted my stream at an
inconvenient time.

John,

Students are being supported through the webcase email system, as our 
agreement with a university for support of students expired, and no one 
wanted to continue to provide student support.

Seems that universities are equally challenged to do things for free.

Since we do recognize and appreciate students using Xilinx parts, we 
chose to provide support through email webcase.

No phones for students (what I was told, but maybe that changed.  I'll 
get corrected if I'm wrong).  Sorry.  Phone calls cost money.  Emails 
are much more efficient.

Spending Real money for a product makes you a customer (not a student).

As such, open a webcase.

It really isn't that hard, is it?

We only get tens of thousands of cases opened each month.

Subject: Xilinx ISE S/W Install kernel version "mismatch"

[crossposted because it's about Xilinx S/W, I'm running Slackware, and
s.e.d is where all the really smart people hang out...]

OK, I decided to take a chance and download that 839MB shell script that's
written for RedHat Enterprise, and was doing OK, (I had to shell out as
root a couple of times to give the install script permission to write to a
new directory, but that felt kind of kewl. :-) ), and now I'm at kind of a
stopper. The graphic install has the progress bar at 99%, and there's a
white-X-in-the-red-circle error message: Error: Cannot run process -
/usr/local/richgrise/Xilinx/.xinstall/install_driverscript 
while simultaneously, the Konsole where I invoked it says:

and the console is patiently waiting (no prompt), and the error dialog box
is patiently waiting for me to click "OK".

So, I wonder, is there some way to spoof Xilinx ISE for Red Hat Enterprise
into thinking that I have the older kernel? Or, maybe (yah, right) that
Xilinx guy who shows up from time to time on comp.arch.fpga might have
some suggestion. :-)

Frankly, I'm kinda surprised that it's gotten as far as it has, running a
Red Hat Enterprise script on a plain vanilla Slackware box. :-) That's
Slackware 10.2, basically right out of the box; and the "Single File
Install" at Xilinx:
http://www.xilinx.com/ise/logic_design_prod/webpack.htm

So, back to the question, can I spoof it? Or get enough source code to
recompile and relink it? I certainly don't want to try to install a
different kernel - that's WAY beyond my scope of "expertise". ;-)

Thanks!
Rich

So, now, I'm wondering, how in the heck do they include a whole installable
package in a shell script? Binary here documents?

What exactly are you trying to learn beyond what can be gleaned from
the datasheets and schematics? If you have the schematics, then you can
create the UCF. You also have the part numbers for all the board
devices, so you can download the datasheets if they aren't included.
>From there, you really don't need anything else for ISE. (EDK may be a
different story, but I haven't messed with that yet)

I wrote my own UCF for the Spartan 3E "sample pack" board, which
admittedly isn't as complex as the board you have, but it's not
difficult. This was my first experience with Xilinx devices, so I had a
few problems with the UCF format (specifically, forgetting to put 'p'
in front of the pin numbers) but I was able to get a working top-level
VHDL and UCF files pretty quick.

Besides, I find going through the schematics to be helpful anyway. It
gets you familiar with the parts on the board, how they are connected,
and any limitations or gotcha's. For example, I discovered that 2 of
the 8 signal lines for MA1-DATA bus on the Spartan 3E sample pack
boards are INPUT ONLY! (Who knows what the designers were thinking when
there are exactly two unused GPIO lines left unused on the board...) I
also discovered that the upper 8 bits of the 16-bit FLASH data bus are
input-only as well.

Now that I know that, I can make better decisions about I/O mapping.

I think there is an option in the kernel which allows you to turn this
check off. But this will need a recompilation of the kernel. By
changing some defines, you can have the 2.4.18-14 kernel compile as a
2.4.31 version. Still, there may be differences in the kernel which
make the software written for the 2.4.31 version incompatible with
version 2.4.18. Somehow Linux developers don't seem to care a bit
about backwards compatibility which makes maintaining Linux software a
real pain in the ass.

I totally agree with you ! I have gone throug all of that, but there is an
error in the schematics. And there is now way I can get support on this
issue, no email support, noe phone support.. I am totally pissed off by
Xilinx, if they dont straighten up i'll cut them lose and left them drift
away..forever.

 Well, $400 is real money for me, I guess like $400 000 is real money for
you ?
Im Sorry, I dont have that kind of money....

If you dont wish to support individual customers,you should not engage in
the retail end of the market. Its as simple as that-you make great chips but
you dont understand the retail business.

I expect to see some improvement in your coustumers service soon.
here is an example of what your homepage should looke like :

Youve got a long way to go, miss Lesea.

Here is a tip : provide information and you will get information back.
Spit the dummy, and you will get ignored...

  Well, others seem able to get answers to questions ?
perhaps, you should work on your skills, and not throw the toys out
of your cot ?

  In engineering, you _are_ going to need the skill of getting 
information you require, and a rant is counter-productive - or do you 
not plan employment in engineering ?

and the point of that rant is what, exactly ?

If you have a specific issue, like an error in a schematic, point that 
out, and it will likely be corrected.

Xilinx are not engaged in the retail end of the market. Their customers 
are designers and engineers. Walmart is a retailer.

Hmm, well, _that_ is a shocker of a web site - all froth, and no 
substance.
I hope Xilinx do NOT copy that.

John,

I have taken a new direction:  when insulted, ignored, and railed 
against unjustly when all I offered was help,  I press "ignore" so that 
I never have to experience your unhappy existence, again.  I can not 
solve all the world's problems, and I must accept there are those who 
are so intent on being miserable, and causing others pain, that I can 
have no positive influence whatsoever.

Good luck.

Nvidia does the same thing with their binary-only drivers, the binary
is included as part of one giant shell script. Perhaps you could
even modify it if you used an 8-bit clean editor...

FYI - the T65 from opencores has known bugs. For example ADC (),Y is
broken. You would be better off getting the T65 from fpgaarcade
(http://home.freeuk.com/fpgaarcade/library.htm)  where this and some
other issues have been addressed. I don't know why the opencores
version hasn't been fixed yet. Maybe the author lost interest in it.

I'm pretty sure that the free6502 (now only available at
http://www.sprow.co.uk/fpgas/free6502.htm - maybe you were thinking of
the patched T65 at fpgaarcade?) has problems. I didn't track down the
exact issue, but if you whip together an Apple 1 like system (we're
talking a few hours work here if you substitute a UART for the
video/keyboard interface) and run integer basic then try running a
basic program like Hammurabi from the Replica1 site, and you'll see
that it has problems. Just too much trouble to track down the problem.
It's an interesting core, so would be nice to see it fixed.

Another possibility is the core at http://www.syntiac.com/fpga64.html
which seemed to work well in my limited testing. (The BusCycles feature
is a little different - I guess that this came from the VIC/C64 world.)

The main problem is that none of these cores include documentation or
verification suites. I would plan on being able to switch different
cores in and out if you run into problems. Kind of a pain since they
are all a little different, but might save pain during development.

Keith
