Hi Fred,
I have no idea if this is appropriate to your situation, but you might 
avoid a lot of the CE compliance issues by using a wall-wart or somesuch 
which is already CE marked. Then all the mains powered stuff is 
pre-certified by someone else. Get one with a ferrite thingy near the DC 
jack!

There is a few hands-on test that I always do to get an idea if my design 
has weaknesses:
-Does it work when I call someone with my cellphone and put the phone over 
my electronics (remember to make noise to get max radiation).
-Does it block my cellphone? You may try a FM radio closeby to see how bad 
it is.. Compare with similar products.

If your project cant afford a test, then its unlikely that you will ever get 
sued for not being within specs. You are just "noise" in the marked.


On the other hand, be sure that nobody can get killed by touching your 
product. And that it doesnt burn down the building if something fails.
Then you can put the CE mark on it and sleep well at nights.

Ive seen some different blasters now and they are all missing ESD protection 
on the jtag pins. A colleague has blown quite a few now. The jtag signals 
only have a small L and then goes direct into level translators that has ESD 
warning in their datasheets. Does anyone know of a protected or opto

Many thanks.  I was already intending to use an external wall-wart.  As you 
say this circumvents much testing.  The total power dissipation is likely to 
be around 3W in any case.

This is for a niche market, though any market has competitors who can play 
informer to the authorities.

It's difficult to justify a cost of several 000s on a relatively small unit 
where the maket may be just 100 per year.

I would put my hand up and say that good safe working practices have been 
followed.  Also the power supply will be a wall-wart, which will have its 
own certification.

Maybe you want to try our EEBlaster:
http://www.entner-electronics.com/tl/index.php/eeblaster.html

Our level-translator have following specifications:
ESD Protection Exceeds JESD 22
=96 8000-V Human-Body Model
=96 150-V Machine Model
=96 1000-V Charged-Device Model
(Because of series-resistors on the PCB, it will be even higher in
real life...) We have heard of no field-failure of any EEBlaster up to
now.

Thomas

Yea thats true, i am sorry.. i did a great mistake on that post, even if it
was not about this subject, this newsgroup is not suposed to be used for
comercial transactions or commitments. Sorry. Is there any way to delet
taht post?

Back to FPGA design... I am using a cyclone II for my design with 208
Pins.. but just Bank 1 and Bank 3 have PCI clamp diodes.. Am i going to
have any problem to use Banks that are placed physicaly at the oposit side
of each other to run a PCI bus? As i am using quickswitchs approach, do i
really need PCI clamp diodes? And is it really recomended to place all the
PCI data IOs (32 bit bus) at the same bank?

Thank you, sorry about my other post again!

Don't bother. They will be more expensive than renting a lab to do
pre-compliance testing. Without a properly shielded cage (which is
difficult to construct anyway) it is difficult to test. For bench
testing a small pick-up loop is much more usefull to identify the
exact source of the excess radiation.

Price modification for duty and taxation is something we can't do for
obvious reasons. We have met the issue of very high taxes in Brazil
before and it's a very big barrier to get getting modern technology
into your country. One thing you didn't say was if this for a
commercial or academic project. We do have academic discounts for
students and universities that pass validation criteria.

On programming cables our USB Prog3 cable is an option with this
board. It operates seemlessly with Xilinx software tools and doesn't
need any other software or drivers other than come with Xilinx
software. It's a similar price to the Chinese option.

However this is extremely unlikely - it is a complaint-driven system, and Trading Standards have
better things to do. 
Germany can be a bit riskier as I believe they do random test purchases, but in a niche market this
is unlikely.

Has anybody ever been done for non-safety critical products failing immunity?
In practice it's a product quality issue. Waving a cellphone near it is as much of a test as needed
to cover 99% of what it will see in the field. 
Immunity testing on something that presents no hazard is a ridiculous and unnceessary expense.

Be aware that most approved PSUs are tested with resistive loads. 
In practice it is easy to make a supposedly compliant PSU kick out noise above limits with a
moderately noisy load.
And of course many cheap supposedly approved PSUs aren't.

the only difference between 'pre-test' and 'final test' is the test house's libility,
A pragmatic approach is to book a day or half-day at a test house, test as much as you can & use the
plots from that to self-certify.

Yes - unless you live in the middle of the arctic, or down a mine,  there is so much ambient that
it's impossible to get any meaningful measurements outside of a shielded anechoic room.

Its for Academic Purposes on Universidade de São Paulo here in Brazil. Can
you give me your e-mail for further questions? I just found out that i wont
have the Quickswiths ICs on my hand fast enough becouse i am going to Spain
at September 19 but would be very good to have the board on my hands 2
weeks before i go and it takes 3 weeks to arrive.  

Thank you!

Just to complement my last post, i think a CPLD board that could work as a
PCI o local bus bridge would be a nice one too. With a very low price.. I
could find one at Altera for 150 USD but i still have to solve tax problems
over here.

Cya!

I would not worry (I used to worry too). The authorities has a lot more 
important work to do than chasing low qty products that has a tiny bit more 
radiation than the papers allow.

They may not actively chase for such products, but when a complaint is
made (by, for example, that competitor) they will have to follow that up.
And although it may not happen very often, I have seen it happen, twice.

And how do you know you're only 'a tiny bit' over the limits without
actually measuring your device? Take a simple oscillator chip and 
connect it to the 'wrong' trace, emissions will go through the roof.

There is no requirement to actually do measurements, you just have to be
under the limits. How you make sure you are, is up to you. If you can
calculate and simulate everything, that may be enough proof you honestly
believe that your device is under the limits. I have not seen that happen,
just measuring is usually simpler.

And even good measurements are not a complete guarantee your device is
always under the limits. These measurements are just scans through the
required frequency range. And if your device produces short burst, they
may be missed in those scans. But at least you have evidence that you
did all you could to make sure your device is under the limits.

Hi,
I am looking for a low cost, small form factor video processing
module. It should have single or dual analog inputs and analog
output(s). A DSP (DaVinci, DM355, Sharc etc) will be required to do
the video processing. Presence of an FPGA is not a must.  Any
suggestions........


Thanks

One workmate of mine has given me a small clue of how the problem can be
solved.

The failing line is at the makefile. The following:

	mb-gcc
-L"C:\Xilinx\12.1\ISE_DS\EDK\gnu\microblaze\nt\microblaze-xilinx-elf\include"
-Wl,-T -Wl,../src/lscqagipt.ld
-L../../empty_application_bsp_0/microblaze_0/lib -mxl-pattern-compare
-mcpu=v7.30.a -mno-xl-soft-mul -o"LEDs.elf" $(OBJS) $(USER_OBJS) $(LIBS)


Here the error is:

/cygdrive/c/Xilinx/12.1/ISE_DS/EDK/gnu/microblaze/nt/bin/../lib/gcc/microblaze-xilinx-elf/4.1.2/../../../../microblaze-xilinx-elf/bin/ld:
cannot find -lstdio.h

which mainly tells that it can not find libstdio.a in the library folder.

I have introduced in windows' environment variables the following path:

C:\Xilinx\12.1\ISE_DS\EDK\gnu\microblaze\nt\microblaze-xilinx-elf\include

but the error remains the same. In that folder there is no libstdio.a as
well as in the rest of the EDK folders...

really i do not know what to do at this point

Best thing to do is contact through the general email boardsales AT
enterpoint DOT co DOT uk. Either myself or one of my team can answer
questions there.
