   So you don't have it.  The first signs I got were both hands going
numb while driving, to the point that I couldn't hold onto the steering
wheel.  The wrist pain came about a year later.  Not everyone notices
the problem right away.  As far as stopping when I am in pain, I would
have had to quit working when I was in my early 20s. I don't recall a
day since then that I wasn't in pain, and all of your drunken ranting
won't change that.  I also have nerve damage in my left arm that feels
like a small, but constant electrical shock.  Unlike you, I didn't try
to self medicate with booze and drugs. I worked as long as I could, but
when I finally threw in the towel, the VA decided that I was 100%
disabled about 40 days from the day I filed.  Their paperwork states
that I will never be able to work full time again, so I think they know
about medicine, and my health problems than you do.

   There you go with your twisted logic. I don't hate myself, but there
are a few people trying to make that list.  The only thing I do hate is
the inability to work 10 to 16 hours a day like I did most of my life. I
couldn't wait for the next challenge to learn new skills and have that
warm feeling of doing something most other people couldn't.  I used to
read databooks to relax, and to find inspiration for new projects. Now I
have to use the electronic versions because I have trouble reading the
small print used in the printed versions.



   Since you love to push that URL, here is a quote of the day for you

                            for he will despise the wisdom

This team boldly set out to provide open source access similar to what
is proposed before getting shut down by Xilinx.

I guess you are talking about the bus macros used to interconnect static and reconfigurable modules. These are available as .nmc files (placed-and-routed macros) in the XAPP290 reference design files. The appnote also explains why they are required.

Recently I had a living room dimmer switch die on me (here in the UK). While 
waiting (10 days) for a qualified electrician, I became tired of the 
darkness in the living room, bought new dimmer, and fitted it. Despite 40 
years of farting around with electrickery, I felt like a very naughty boy. 
I'd done the calcs, but I mostly work with microamps and nanoseconds.

Weirdly enough, I can see the logic. I once lived in a house that a

There are alternative ways for the government
to handle these issues and still provide for
a safe environment.

I live in the US and I installed a 50 ampere,
240 volt subpanel in my garage by myself and
I am neither a licensed electrician or engineer.

The city required me to file and get approval
of a permit, which was a simple drawing showing
wire types and sizes and the grounding scheme.
After I did the work, an inspector came out
and checked it.  I had to write the city a check
for about $50 for the permit and inspection.
A good deal considering I would have had to pay
a "professional" somewhere between $750-$1000
in labor to do the job.

Do you guys still go around and turn off all
the outlets at night?

It used to be (here in the UK) that a) *.* would do the wiring, then b) an 
official from the Electrickery Board would come around and sign it off, for 
a "nominal fee". In theory, great. In practice, said official would be 
unlikely to raise floorboards - some would, some just wanted to get off down 
the pub.

Nah. Nowadays I have kWh meters on the outlets. If I turn them off, they 
start over.

What version of ISE?

Are you using the unisim library like this:
 library unisim;
   use unisim.vcomponents.all;

Or, defining the component yourself?

Instead of using the named suffix I/O buffer, try sticking an
IO_STANDARD of LVDS_25_DT on an input buffer of type IBUF{G}DS

Problem is that having a higher than 99% literacy (or a 99.3% iirc) is
very hard to impossible to achieve. And the problem is not so much the 
education system but peopel who have medical conditions that make it 
impossble for them to ever become fully literate and those who have
willfully avoided the educational system or it fruits.

Go to "the secular democracy" Turkey, remind them of the Armenians I am sure
they will explain in a robust and summary manner how wrong you are. In only
a few weeks you will be back on a diplomatic flight. That is the ways of a
luser culture!!

Boosh want them very same Turks in the EU - Why?? Well, on this side of the
water we have come to understand that what Boosh wants is what is good for
Boosh not necessarily anyone else. The Europeans O.T.O.H. knows that if one
cannot integrate even a few million Turks in the EU, then 50 Million++ is
going to be ...err... a challenge.

I.O.W. what Boosh really wants is to eliminate a potential competitor
bidding for The Oil (and probably suck up to some Saudi islamist claim on
Europe up till Vieanna, which is how hide the tide reached last time we
kicked them out).

You right Peter,

I am not fair. The life isnt either.

But I am not making anything up. This is something I do not do. (Sure I am 
wrong sometimes, that has happened).

1) All my latest WebCase's are handled from China or at least from people 
with chinese names.
2) someone else (I assume from US) reported the same for his 3 last 
WebCases, he also called and reached answer machine in chinese.

So thats why I assumed that the _global_ WebCase support has been moved to 
China/chinese. What I said was/is true for me as to my best knowledge of the 
time of my writing. I did not pay attention to the WebCase email names until 
someone else pointed my attention to it, then I looked at my cases and I had 
to agree that its all handled by chinese now. Maybe it isnt, and it was just 
a co-incident. And sure a superior suport could also be provided from china. 
Nothing wrong with.

All I was about to say is that I have even less trust (in timely resolved 
issues) from Xilinx websupport then before (before == when EU support was 
handled from Ireland and not from China). Maybe China support will be 
better, only time can tell that, but for the time being I feel that I am my 
best Xilinx FAE as in vast majority of cases I have had to fix the Xilinx 
related issues myself.

Like yesterday - I take OPB_SPI core, I set SPI clock ratio, send out 2 
bytes to SPI. Works with loopback testing. But with external SPI flash it 
doesnt work. After hours and hours troubleshooting I connect oscilloscope 
onto SPI clock and what I see? 7 clocks are normal with programmed clock 
width then clock pulse of 20 nanoseconds, then again 7 normal clocks and 
again 20 nanoseconds pulse. Sure this works with loopback test code provided 
with Xilinx.

For heavens sake there should a way to get something as simple as SPI master 
to work without the need of connecting an DSO to the FPGA !? I could not 
belive that 20ns pulse (1 OPB clock). OPB_SPI is part of EDK for long long 
time, how come this is possible? Has anyone used it before ? Ok, later on I 
found some xilinx AR as well, talking about clock glitches when data and 
clock change at the same time. But when I use EDK, and EDK IP cores, I would 
expect that at least the simplest ones really work, without the need of 
scoping the signals or searching AR database for related issues. Or is it 
too much to hope for?

If you work with Xilinx products then things like that happen every other 
day almost.

I talked about this thing with the fellow engineers around, their comment 
was: "well thats how they do it, let you to find and fix their problems". 
Sure this is how MicroSoft does it. This is why so many hate MicroSoft. I 
like FPGA's. I like very much. But my tolerance level of accepting bugs and 
erratas is getting lower and lower. I am not getting paid to find bugs. So 
arent others who open WebCases and help Xilinx to fix their products and 
services.

I have stated many times that I could be very valuable testing Xilinx 
software and helping to improve it, I think others here at c.a.f. have made 
suggestion that I should have early beta test access. I do not. It took me 3 
minutes to cause fatal crash close of ISE 8.1 after it was released. If the 
Xilinx Software goes worse the same rate, I will never install ISE 10.1 on 
my workstation.

So I am getting more and more frustrated seeing more and more issues with 
Xilinx products and services. Issues that take my time. Time that I would 
rather spend with my family or just doing my job, which currently isnt bug 
hunting.

I am still energetic, and I would love to use all of my smart imagination to 
improve Xilinx products, but being on the field and just fighting with the 
Xilinx bugs (while it isnt my job) is not helping Xilinx much. It hurts. 
Anyone.

I would like to help, but I just dont how.

I have setup open public access bug tracker database where I will enter all 
the bugs with Xilinx products that I will find. In a small hope that it 
helps others to save their time to avoid the issues or apply workarounds if 
those are available.

Does that mean we will see either total power or derating curves for
LUT/FF toggles to define power and thermal limits as both a percentage
of active logic or size of the active design?

While you may not see this as important from a perspective of past
uses for traditional hardware design, as reconfigurable computing takes
off there is a completely different mindset hitting your market.
Software
tools WILL be packing active algorithms into devices to get the best
computational effciency per device. Good packing WILL yield close to
100% active logic in a device, and yeild exactly what you are mocking:

Devices that are by design not expected to be more than 10% active will
greatly disappoint their customers. You will increasingly see large
applications reduced to netlists which have a very high toggle
percentage. The user will see that his application compiles to X number
of LUTs, and will be buying devices with just over that number of LUTs
to run the application. If the user does not encounter a clear warning
to derate the device, then we have a truth in advertising problem.

Something akin to purchasing a family car advertised to cruise on the
freeway at 75mph with an economy of 35mpg. Customers will not find the
car acceptable, if it can only be operated at those speeds for 10
minutes, and require a 50 minute inactive period on the side of the
road to cool down because some engineer decided to save a few
horsepower by removing the water pump and the rest of the cooling
system. Cars are assumed to have short term duty cycles in hours, not
minutes.

While hardware design engineers may have grown used to the omissions in
the data sheet about duty cycles for FPGAs, the new reconfigurable
computing market is going to be much less tollerant of devices that can
only be operated with a 10% duty cycle, or at 10% of rated capacity.

If the data sheet says 1M LUTs capable of 800Mhz, then that is what is
expected by end users looking at the data sheets to purchase FPGA's for
computing. If the device is really only capable of 10% of 1M LUTs at
800Mhz, then from a reconfigurable computer perspective it's really
just that, a 100K LUT device, not a 1Mhz LUT device.

Likewise, if there is only one routing solution that will achieve 100%
utilization of the device, and a typical reconfigurable computing
netlist will be route limited at 65% utilizaton, then a 1M LUT device
is NOT a 1M usable LUT device, but rather only a 650K LUT device for
typical reconfigurable computing uses.

So, this is not the 1980's any more, or even the 1990's ... a new
emerging primary market for FPGAs is reconfigurable computing and we
need devices which are clearly specified for worst case loads that will
be typical ... not the exception ... in that market.

Im designing a module working as an fm0-encoder, the clk and max
datarate of which are both 640KHz. It is not complicated when the
datarate is lower than 320K, the half of clk. But when the datarate of
640K, the clk frequency, is concerned, the problem comes that I have to
change the state at both the rising and falling edge of the clk. Now I
am using a mothod via combinational output, which is not so good and
expansible as registered output using an FSM. I think that an FSM using
DET(dual-edge flip-flop) would work, but I am not sure wether it is
recommandable to use det and I don't know how to describe a det using
synthesizable Verilog?
It would be appreciated very much if some of you can
*comments about the det method,
*the methed about how to describe a det flip-flop

Hello,

I get trouble to run a project(synthetize and p&r)  It complete sucessfully 
all the steps but it doesn't validate it so when I try to remake just one 
step like the P&R it restarts also the synthetize as it has never been 
done. Also when I made a step instead of putting a green mark on this step 
when it have been done , it puts a a point of interrogation ( and not a red 
cross)

for example :
I make my project and synthetize it . ISE says me that it have been 
completed but it keeps the point of interrogation. Then I run the Implement 
Step and it restarts the synthetize first. As if I have done a a rerun 
command.

If I make a full run (synthetize+translate+map+P&R) It validates all steps 
when they are finish (but still running the next step) with the green mark 
but when it finish the run all the step are unvalidate ( by a ? sign)

does anyone have already meet these problem?

I have already try to reinstall ISE (6.3 sp3) and remake all the project 
(just keeping the vhd)

Thanks you for your answer.

  That's quite a large leap, Antti, from 'Chinese name' to 'Must live in 
China' - did you check the email time tags, that often gives a clue to 
the time zones you are working between ?

maybe I mis-judged. I havent checked the email header time tags. Some else 
(also having Xilinx issues) was complaining about the answer machine on his 
WebCase contact to respond in chinese, so I checked the names from emails 
and found his assumptions about the WebCases now being handled by people 
with chinese like names to be true.

Maybe I am too hard at (Xilinx WebCase support) as my issues are usually not 
such that the WebCase assigned person has any chances to help. He always 
needs to contact others and that makes it really long to get some meaningful 
response. So I do not really have hopes that a WebCase helps if it is not 
'accelerated' but then ah, it makes possible more sense to immediate 
'accelerate' the issue, and that is something that Xilinx doesnt like of 
course. But if immediate acceleration of an issue brings the solution even a 
few hours faster then it is a few hours won.

I am pretty sure that there are people at Xilinx who are thinking very 
seriously how to actually improve the software, support and services so lets 
hope it will get better. There is lots of space for improvements, in all 
areas.

It is not difficult to driscrobe dual-edge flip-flop in an HDL.
The real question is: Can you build them in your target technology?
Most FPGAs do not have them and most standard cell libraries do not
have them either.

I doubt if I qualify as a food snob. I'm a bit too willing to eat a
good pizza - particularly since the cute Italian post-doc charmed
Nijmegens good pizza place into stocking Amarone (which lead to us
paying twice as much for the wine as for the pizza, until the
proprietor realised that if his pizzas were good enough to eat with
Amraone he could get away with charging more for them).

But not too fancy. With two Michelin stars they can do everything
perfectly, but are unlikely to surprise you. For three stars, they need
to do everything perfectly and be inventive to boot - though three-star
restaurants in France can be a bit dissappointing for a few years
before the inspectors finally lower the boom. The owner-chef of the
restaurant de la Cote d'Or in Saulieu - Bernard Loiseau - shot himself
after the Gault Millau guide downgraded him from 19 points to 17, so
you can understand the reluctance of the inspectors.

Frank, you very Dutch! The service and the ambience are just the
wrapping paper around the food. Of course the joy a group gets out of
eating together is only incidentally affected by the food they eat, but
the food is what the restaurant is supplying - the joy we have to find
for ourselves!

Guys

Does anyone know whether ISE simulator lite will simulate the RocketIOs
on the virtex 4 that webpack supports?

I have a simulator that doesn't support smartmodels so I could live
with the poor performance of simulator lite just to check the rocket IO
bit of my design.
