Hi, As I did have some strange experiences with SOPC_BUILDER that look like a problem you actually have. My first mistake was to place the SOPC_BUILDER at some place where it would have make sence. Don't do that. Keep the suggested directory. Second mistake was, I uninstalled the SOPC_BUILDER and reinstalled it to different directories... There ist somewhere a file where the path to SOPC_BUILDER must be set correctly. Unfortunatly I don't rember which file it was. Third mistake, Cygwin was not installed. There is an cygwin enviroment delivered with SOPC_BUILDER but it did not work for some reason on my computer. Fourth mistake, I did not install the perl program delivered with cygwin. The one delivered with SOPC_BUILDER was not working. Fifth mistake, when installing cygwin, always select that your files are in DOS LF mode. Otherwise you'll get compilation errors... I did get them anyway but that's a different story. Last hint, make sure your enviroment variables are all correctly set. Good luck, KarstenArticle: 57728

I appreciate the effort. I hope I can count on an answer from someone. I don't remember exactly when I called about this question, but it was over a week ago I am pretty sure and may have been two. BTW, the only options for support are the web page which requires the use of a form and agreement to a very long and difficult to read (on the web) terms and conditions. Is there some reason that Altera can't provide a simple email address for support? The web page does not allow me to track the issue on my system as I can with email. To be honest, it is unlikely that I will sign up for the online support given the way it works and the long agreement form. So instead of using email, I will be using the phone which I am sure is not Altera's favorite choice. > The other question about quiescent current: > Your interpretation is correct.

Thanks for the answer, but you listed the -3 indust/extended devices in both camps. The -3 parts are all 5 mA, right? Not that it matters a lot. The -3 parts don't provide fully functioning PLLs so I am specing the -2 parts even though I don't need the speed. Thinking about how they are specing this parameter, I realized that there are likely no EP1Kx-1 industrial parts or they would likely be 10 mA parts as well. BTW, I tried looking this up on the web page, http://www.altera.com/products/devices/common/dev-avail_device_search.html But it returned a .pl file type which the current version of Netscape does not understand. Is this a bug in the web page or a bug in the browser? When I looked this up in IE, I found that there are *no* EP1K extended temp parts and the EP1K industrial parts only come in -2 speed grade. Is this right? I guess that is another reason to not use the -3 parts. > rickman <spamgoeshere4@yahoo.com> wrote in message news:<3F047811.D824824C@yahoo.com>... > > Since Altera seems to be active in this group, I will ask the question > > here.

That is 64 IOs at once and each one sinks current. Seems the total current sets the limit. I tried to get more detail on this to find a way to use it with the PC/104 bus, but they kept telling me to consider a different family. Oh, well, I guess I have found another family, it is not a Lattice one however. > On some devices the IO tolerance is spec'd also CORE relative, so > you can get caught if your IO power is present, and the core > voltage is not! On both the Lattice LCxxxx lines and the Xilinx XCR3xxxXL parts the 5 volt tolerance is not there when the voltage is not there (Vio in the case of Lattice, IIRC).

In the case of the Lattice parts your static current is much higher with the internal regulated parts. If I want to use an LDO, I can get a unit with <100 uA of standby current, a major improvement over the mAs of the internal versions. I was going to use the 2.5 volt version since I have a switcher generated voltage available and this would improve my efficiency over the 3.3 volt version. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address.

I don't see any reason to expect the LC4000 (which is what I believe you are calling Mach 4000) will not be here as long as any other PLD family. This is a sound part and has some very good features. As to price, I have gotten much better pricing on the Lattice parts than I have on the Xilinx CR ones. Once the size gets up a bit, the CR parts get very, very expensive. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address. To email me use the above address with the XY removed.

You are looking at using some 30 to 100 parts on your board. The distis have to deal with thousands of parts every day. It is very hard for them to keep up with what means what in the part numbers. It is much better if you tell them the variations in part numbers that you can work with. Normally the only option you have is a faster speed or a wider temperature (which often does not make a part *more* available). I have been able to give them a starting part number and tell them that this letter is a don't care and they can tell me what is up with inventory and product volume. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address.

But can you be sure that it's completely standalone and won't need any QA? Have you changed any of the toolchain used to build the tools themselves?

But the same people who can write those scripts can make multiple ISE versions co-exist; it's trivial. I suspect it's the GUI users complaining about old tools being dropped.

Feature request: more BUFGs. Grip: differential clocks take two global clock pins. It would be better if they took one global clock pin and the other pin in the differential pair was a standard I/O pin. I don't know if that is feasible, but differential clocks chew IBUFGs quickly. On the project I'm currently working on we ran out of global clock pins this way and put one of our clocks on a non-global pin. Works fine. Our experience shows that it's preferable to have differential clocks even on non-clock pins than to use single-ended clocks.

I wouldn't mind either, but they are licensing the GUI libraries from another company and they have to pay a substantial sum of money per copy of Quartus [whatever edition] running at a customer, so they won't be giving a Linux GUI for free.

I am sure both are just parroting whatever is the original source of the info. I could not get them to give me any more detail, such as what effect a series resistance or other source impedance would have on the spec. From the FAE... "You are correct, the 5512MB does have a limit of 64 IOs that can be driven above 3.6V. This is due to the leakage current that appears when an input is biased above VCCio. They need to keep the total amount of this leakage current below a certain number and that worked out to 64 IOs." From support... "The 64 IOs 5V restriction is a reliability requirement for EE9 technology to ensure that we meet oxide FIT rate requirement." You could do your own testing on a device, but how would you know that this will be consistant across future versions of the device? It is not at all uncommon for a company to alter their process while keeping the original published spec. Xilinx has discussed this recently on the SpartanXL. While they maintained all the publised specs (and improved some), anything that you have tested in the past may no longer function that way. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address.

Hi, all, I am implementing an on-chip 16*32 CAM using Xilinx Select RAM(applicatin notes 204 or 260). I am wondering why a register is added to each of the input and output. When I simulate the design in Modelsim, there is always two clock cycles' delay, one for the input register and one for the output register, I guess. So if I specify the data to match, the match output signal will appear after two clock cycles. I don't think it is a correct implementation. Any one has idea about this? Thanks for your answers! regards, AlexArticle: 57749
