Hallo, someone could explain what is syncword? Is the prom address? If I use a flash XCF02S (2 Mbit) and fpga bitstream is 1Mbit, what number should be syncword? Many Thanks in advance MarcoArticle: 88604
Peter, It has been awhile, It took awhile but have understood your concern good advice. Some of my best case jitter has been an order of magnitude better than the worst case scenarios given app notes and the DCM wizard. I write because I wanted to confirm that this is not the case for the buufered output of the DCM, namely, CLKIN_IBUFG_OUT. This is merely a input clock buffer, used for high clock fan out, as I understand it. My question, Peter, is there any jitter attached to the ibufg componenet, and using this output from the DCM is not constrained by the DCM jitter problem, right? thans CyArticle: 88605
I think it's the Texas Instruments TFP501 and TFP510 (Rx and Tx) that are popular TMDS choices. These came up with similar parts using a keyword search on DVI on the TI website. I like the 12-bit DDR interface option for the Spartan-3 parts, personally.

Cool ;) For the obvious : Some DDR is a must (A memory socket on the other hand is not that useful imho), as well as an RS232 level uart and a network interface (with a auto mdi/mdix phy would be nice ...) Video outputs, as suggested video output would be great. I think that it would be nice to have both digital and analog. The ADV7322 looks nice for the analog part. Another useful stuff would be a AC97 codec like the UCB14xx, they provide Audio IN / Out with mixer etc ... That one even provides a touch screen interface ! What about a PCI slot in which you could plug stuff in ? Also don't forget a flux capacitor. Event thought it's originally design to be mounter on Dolorean, I'm sure it will fit (just be aware of the current requirements ;) SylvainArticle: 88608

These are available cheaply surplus, and great fun to play with, but the easy-to-drive ttl-interface ones are much harder to find than the now near-universal LVDS panels. (Data rate is probably too high to drive the LVDS directly from the FPGA) You can never have too many switch inputs to select modes etc. when experimenting - BCD rotary switches are useful here.Article: 88609

Before you spend too much time screwing around with Hyperterm or other serial programs, have you looked at the signals from your fpga board to the serial input of your computer? Start with no serial cable, and check that the TX pin (when no characters being sent) is -5V to -15V. The RX line should be floating close to 0V. Check the two pins that TX and RX connect to on the computer (pins 2 and 3 of serial port connector). The one that your FPGA TX is going to connect to should be an RX pin, and it should be close to 0V. The pin that the FPGA board's RX is going to connect to (computer TX) should be -5V to -15V. Then to check that you have hyperterm set up right, with nothing connected to the computer serial port, type on the keyboard. Nothing should appear. Then connect pins 2 and 3 of computers serial port. Now typing should echo. On your FPGA board, change your program so that it just continuously send a "*" character. Connect a scope to the FPGA board's TX signal. Check the timing makes sense. Do the same on the computer (hold down the "*" key), and look at what the computer is sending out. The characters should look like what you got from the FPGA board. Until ALL of what I have written above works, there is no point in connecting the FPGA board to the computer, and complaining that it "doesn't work". You need to do the above to localise where the problem is. Philip Philip Freidin FliptronicsArticle: 88610
Unfortunately we seem to run of Flux Capacitors. We burn out the last we had doing the first MINI-CANs which we delivered from design start to fully tested working prototypes, on customer site, in 18 calendar days. If you come across a good supply let me know as I like to see the Enterpoint keep on meeting these impossible timescales that some of our customers demand. Back in the real world I will have all these interfaces looked for either the Raggedstone1 or module inclusion. Some of what you want is already there in the Raggedstone1 but I will let you guess what. John Adair Enterpoint Ltd. - Home of Broaddown2.

You will be able to have BCD switches in RS1 in a similar fashion to Broaddown2 through DIL Headers. The LVDS area we are looking at for a customer project already and depending on results there we make some kind of implementation suitable for RS1. If there is enough interest I will see if we can do a TechiTip on it. John Adair Enterpoint Ltd. - Home of Broaddown2.

At least for medium sized panels. Even if it's too high for "direct" implementation of the serializer, I think I saw an application note at Xilinx where they used the DDR registers in the IOB so that the internal serializer logic only runned at half the serial clock speed. I wish I had some hw to test that ;) SylvainArticle: 88614

Hi, Have you tried resetting the 2nd DCM while the 2nd DCM has a valid input clock? I'm not claiming that user logic resetting the DCM is mandatory, but trying this may give you some more information. (I had a simulation issue recently where i needed to reset the DCM to get it running again - I was mucking around with the DCM input clock though so its probably not surprising...) If you are using modelsim you can use your testbench to "force" a reset on the DCM input. This means you don't have to modify the DUT design. See below. library modelsim_lib; use modelsim_lib.util.all; signal_force( "/toptb/dut/Reset", "1", force_type => freeze); Obviously you will need to replace "/toptb...."

what i mean is the package. for example, xilinx starter kit includes JTAG cable , power adaptor, etc. are they includede in the digilent board too? thank you CMOSArticle: 88621
It's the exact same thing. Same cable, same software, same power supply... same box. And, they're both the same price. I bought one from the Xilinx website.

yes, if you buy it from xilinx, you will get all of it. but if you buy it from digilent, you will not get the evaluation software. im not sure whether im getting the other parts like JTAG cable and power adaptor if i buy it from digilent. I prefer to buy it from digilent, because i want to have a better device with atleast 400K gates. Im not sure whether the starter kit is available with a better device.Article: 88623
You don't have to close impact, just make sure that you close the cable connection using Output/Cable Disconnect. After upgrading to Chipscope 7.1 sp3 these sorts of problem disappeared for me.

Hi Guys
I was able to implement Genetic algorithms on software.
Now I am taking my project to the next level by simulating hardware
like logic gates (AND,OR,NOT) as classes in software.
Then I can create objects of these classes and evolve a circuit with
the help of these gates. Maybe evolve a NAND gate. I think it is
feasible but I would like your suggestions on this idea.
Your suggestions did help me completing the previous software to solve
an equation genetically.
I was just wondering how should I represent a circuit in the form of a
chromosome('010011010' or 'A!B&|C').Mutation is the next process and
what could possibly be a fitness function.
