This group is filled with much expertise and most participants are MORE than
willing to help in anyway they can. I've seen them give students answers to
their homework, and give engineers help with debugging and overcoming design
hurdles. The only thing any of the aforementioned SME's expect is that
those posting questions would be polite, truthful, and professional.
There's a wealth of knowledge on this board that is made available to anyone
earnestly seeking answers.
There's an old proverb which says that "a wise man will hear, and will
increase learning, and a man of understanding shall attain unto wise
counsels". You've done properly by contacting this group (wise counsel),
but unless you are willing to HEAR and listen to that wisdom you're nothing
more than a fool.
Here's a piece of advice: stay humble, don't react when filled with emotion,
and be willing to take criticism.

Just FYI: it qualifies him as someone whose first language wasn't
English, making him particularly sensitive to the issues faced by those
who try to communicate on this board with an excellent written word but
who miss the more subtle meanings in these newsgroup communications and
in technical documentation.

You want me to be polite, going by this answer.
My first language is none of your business, this
remark could qualify you as something, I won't say to save
you the embarassment.

As per usual in this news group when people don't get their way

I asked if you looked at Solution2 for that Answer record. By the "I
couldn't find it no matter *how* hard I looked tone in your response, I
figured you had trouble connecting simple images and phrases with the
information being conveyed. I thought that if I cut & pasted the quotes
for the 10C value USED IN THE ILLUSTRATION IN THE ANSWER RECORD that you
would obviously get confused. So I requoted the text to show the "7C"
you have on your part. I only mentioned the "10C" to avoid having you
say that the text I quoted wasn't in the Answer record.
Additionally, the xc9536 data sheet on page 7
http://direct.xilinx.com/bvdocs/publications/ds064.pdf
shows the device marking explicitly calling out the "Speed" number.
You appear to not bother 1) read the data sheet, 2) read the answer
record that was provided to you as a link, and/or 3) prefer to have
everything handed to you in such an outrageously clear fashion that a
third generation tropical island castaway would understand what the
marking on the device meant.
We helped. You returned, helpless. You complained.

Maybe English is not your native language:
The little word "and" at the beginning of the sentence changes a
slightly pestering question to an obnoxious statement.
If you are as ignorant in this technology as you seem to be, it would
be wise to be more polite.
Any answer you get here from anybody is because we want to be helpful.
Keep that in mind!

7 ns, Commercial grade.
Changing the "10C" to "7C" in the illustration to match your part would make
the following text applicable:
Line 4
Device speed grade (7) and temperature range (C). If a grade is not marked
on the package, the product is considered commercial grade.
In addition to the mark shown above, Line 4 can contain a few other
variations as described below:
7C xxxx
The "xxxx" indicates the SCD for the device.
An SCD is a special ordering code that is not always marked in the device
top mark.
7CES
The "ES" indicates an Engineering Sample (as opposed to a production
device).
7CESn
The "n" is a numeral (1, 2, 3, etc.)
The "ES" indicates an Engineering Sample, the "n" indicates an ES revision
code. For example, ES1, ES2, ES3, etc.
Please see Errata for appropriate information. To obtain Errata, you must
register for MySupport, see (Xilinx Answer 21491).
7CESnL or 7CESnR
This part marking is used only for Virtex-4 FX engineering sample devices.
The "L" indicates that only left (column 0) MGTs are available and the "R"
indicates that only the right (column 1) MGTs are available when looking at
the device from the "bottom-up."

Did you actually look at Solution2?
You may not be using Virtex-4 but the rest of the lines appear verbatim
correct to your description.
