I just wanted to post an update to this problem. I was contacted by someone from Xilinx technical support some time ago and I just got a confirmation that they are investigating the cause of this issue. The recommended workaround is to turn off FSM extraction. 1 point to Klaus for recommending the same workaround shortly after I submitted the original posting :) /AndreasArticle: 115926

While both Device/package combinations are listed in the datasheets, I have not seen any of these devices "out in the wild" (means available with Digikey(*)/Nuhorizons/Avnet). I bothered Xilinx people at both Electronica 2006 and Embedded World 2007 about availability/plans for availability for these devices, but never heared back. Does anybody have more information about these device/package combination? Thanks (*) Digikey list the XC3S4004PQ208C as available on demand with minimum order of 120 pieces. -- Uwe Bonnes bon@elektron.ikp.physik.tu-darmstadt.de Institut fuer Kernphysik Schlossgartenstrasse 9 64289 Darmstadt --------- Tel. 06151 162516 -------- Fax. 06151 164321 ----------Article: 115928
Hi,
First, thank you very much for your idea. I got some interestings
thing from you. I have just come back my work from long holiday in my
country.
I compile 2 example file. Example_Sqrt is ok, But i have problems with
fibonacci file. when i compile file fibo.psm
i have the following screen:
01E LOAD ZH, 00
01F SUB YL, 01
020 STORE ZL, (YL)
021 FETCH ZL, _N
022 SUB YL, 01
023 STORE ZL, (YL)
024 CALL _outchar
025 ADD YL, 02
026 ; Fibonacci_result=Fibonacci(N); // calculate fibonacci of N
026 FETCH ZL, _N
027 SUB YL, 01
028 STORE ZL, (YL)
029 CALL _Fibonacci
ERROR - Address is not 3-digits: _Fibonacci
Provide a correct absolute address in range 000 to 3FF or
a matching line label. Note that labels are case sensitive.
Please correct and try again.
KCPSM3 complete.
Can you show me clearly again!
I know, my questions may be stupid. But i think" wanting to know must
to ask"
please help me,
Him Lam

Is there a way to access the platform cable USB from a user program (i.e., from outside the Xilinx toolchain) ? What I'd like to do is access a BSCAN module inside my design from a custom win32 application. Many thanks, Guy.Article: 115932

On each iteration, the xilinx linux support for webpack seems to get better and better. The only issues I've had as of late are related to running the 32-bit webpack on amd64 hardware (it works, I just have to edit a single script file.) If you're having trouble downloading webpack in single-file format, I might suggest trying wget. When you get the list of options of files to download, copy the url and from the command-line run: $ wget http://urlforwebpack at 1.4 GB i've found this to be a more robust way of downloading. Please let me know if you have any other questions, and good luck! ...EricArticle: 115933

Directly from the Xilinx website, I've been getting issues with these, whether it's the single file download or the web install. 9.2i installer gave me a bus error and with the older versions the script files gave me some checksum errors as I said before (wget or otherwise). I found some old mirror site http://www.tx-g.net.hu/files/xilinx that had the files for 8.2i archived. I tried the WebInstall version from there (as it's a smaller file) and it actually opened, but the install didn't succeed. This led me to suspect that the single file install from this mirror would probably work ok for me. It is a slow server and took over 3 hours to downoad (against 20 minutes straight from Xilinx) but the install worked! I do have an AMD64 Athlon processor, so I may be interested in hearing your script file edit. Is it the settings.sh, Display:= 0 thing that I've been seeing around, or something else?

I am new to FPGAs and Xilinx Virtex 4. How do I create a 100khz clock signal?Article: 115937
On Feb 26, 9:26 am, jim <-...@-.-> wrote: > I am new to FPGAs and Xilinx Virtex 4. How do I create a 100khz clock signal? The very first step is to figure out the required accuracy and stability. High accuracy or stability requires an external crystal oscillator and probably a divider. Low requirements can be satisfied with an external RC circut. Peter AlfkeArticle: 115938
jim, With a 100 KHz clock source. OK, seriously, the DCM can only divide an input clock by 15 (or 16, I forget) on the CLKDV output, and since the minimum input CLKIN for this feature is 24 MHz, that will not get you down to 100 KHz. The alternative is to use the CLB DFF to construct a divide by N (whatever you need) counter, and put the clock you have into the BUFG clock net (from an input pint), and take the clock out of the MSB of the counter (divider). External clock sources which are crystal based are easily obtained for less than a few dollars. These have frequencies from 5 MHz to 100 MHz at fairly low cost. Above 100 MHz, the oscillators are more exotic, and cost more. In is not recommended to try to attach a bare crystal to IO pins to construct an oscillator. AustinArticle: 115939
Hello All, I have a Xilinx ML501 board and I want to use the Xilinx XCF32P platform flash to configure the XC5VLX50. I can program the LX50 directly accross the JTAG chain and the design runs correctly (flashing LED's). Also the XCF32P does show up on the chain and Impact lets me program it. Unfortunately, when I hit the program button my design does not come up. The done LED goes true after a delay as if the part is programming from some other source. There is a 8 position dip switch on the board, SW15, that apparently controls the configuration source but the documentation is not clear about how to set that switch for platform flash. I have all zeros selected now. Can anyone just tell me how to set SW15 to configure from the platform flash on the ML501? Thank you, Pete DudleyArticle: 115940

Could some one give some information on ICAP.I have read thru the documentation on www.xilinx.com on dynamic reconfiguration,I still have not understood how would I access the ICAP port?I am basically trying to use the PowerPC on the virtex 4 to dynamically reconfigure the FPGA.I am also looking to synthesize a Microblaze softcore and make it do the reconfiguration. So in short Here is my specific Question .How do I access the ICAP?Does it have a port address?Say I write a C+ + program running on the microblaze,my intension is to change the bitstream dynamically by using the ICAP. Thanks for the Information! Best Regards,Article: 115942

Hi Antti, Yes, seems quite broken. Someone in Xilinx did _test_ this, right ? Lets hope that their design and verify flows for their silicon are of a considerably higher standard than their Web pages ?! Whilst we are waiting for Xilinx to get their act together, perhaps you could give your thoughts on what's new in the 3AN series, appart from just dropping some flash into the package ? -jgArticle: 115946
prasad, You instantiate it as a component in a design, and wire it up to other things inside your FPGA. It acts a a means of allowing the inside of the FPGA to talk to (listen to) the configuration plane. The ICAP is part of the SEU solution (all config cells are readback, and corrected if in error), and also for other interesting applications. If you want it to be an I/O on a processor, then you need to design a simple I/O port interface to it. AustinArticle: 115947
Cat out of the bag? Well, sure looks like the website folks are going to have some embarrassment from this. Yes, that link is certainly broken. As for 3AN, I have to wait until the release to talk about it, unless you were already one of the "early adopters" and are under NDA. In that case, you already know everything. AustinArticle: 115948

Get a circuit like this one :- http://www.longwave.de/lfregen.html Tune it to about 198kHz, and throw away the low pass filter bit that drives the headphones. Take it to Droitwich in the UK. You'll easily receive Radio 4 long wave, there's a 500kW transmitter there. Connect signal to Virtex 4. Use a flip flop in said FPGA to divide the 198kHz carrier clock by 2. This gives you 99kHz, near enough, I expect. Here's a link. http://en.wikipedia.org/wiki/Droitwich_transmitting_station Looks like you're 18 years too late, the frequency changed to 198 kHz from the perfect 200kHz in 1989.
