Although the ASIC can be tested to a degree assuming a sufficient BIST, it is alot easier to test an FPGA then monitor its condition with periodic readbacks of the configuration program. Based on the arguments I've seen to date against using SRAM based FPGAs, it seems the real reason is ignorance of the device characteristics and correct configuration methods. -Ray Andraka, P.E.

Note that most systems and made up of more than "100 such parts". Certainly, the overall safety of system must be judged from the reliability of ALL it's parts, including the pilots and all the tests and checks that are done. Pilots chosen seem to have a lot of physical and mental skills that most of us don't have, such are better eyesight, better body condition, etc. Even here you have the backup of a co-pilot. If you look at the whole system, certainly there are airplane incidents each year but the accident rate is probably a lot lower than the auto accident rate. It's a lot safer to ride a plane than a car. The problem for the designer is that he or she must also claim high reliability (preferably backed up with some data at a design review) of the bad load problem. This is for all situations over many packages. This is probably not worth their time except under some unusual circumstances. ######################################################################## Alvin E.

Hi, I've found the easiest most flexible solution is to use a constraint file (.cst). This allows your constraints such as time specs and pin allocation to be done in a separate file which is easier to modify than the full VHDL code. See the Xilinx online documentation, Libraries, chapter 4. Hope this helps.

Is this an appropriate newsgroup to post PLD questions? (I have a problem with a Lattice PLD) Tom SmythersArticle: 4831
Hi! Does anyone know any architecture based on FPGA for a fast digital signal processing? Please, answer me at the below address. Thank you. Email: jangomez@unex.es URL: http://maxwell.unex.es/CALDArticle: 4832
Hello, first time designer here. I've got an application that takes a serial 200 MBit/sec data stream that has a frame length of about 1024 bits give or take a few, frame sync, and is time-division multiplexed. The task is to frame sync and then deinterleave the data depending on the TDMX mode we're in (there are a few). I've done a little research so far, and there are devices by both Actel and Xilinx that will do the trick in that regard. I believe both are FPGA's I understand the difference in generalitiex between CPLD's and FPGA's, but is one better than the other for specific applications? For my application there isn't a lot of high level stuff going on; other than the frame sync process, I'm counting bits and sending them off to different outputs. As I understand it, CPLD's have a lot of simpler blocks with a very deterministic prop delay setup, while FPGA's have more complex blocks but the prop delay's are not quite so rigid. Am I looking in the wrong direction here towards FPGA's over CPLD's? Are the CPLD's faster? Am I totally wrong about counting bits being a low level sort of thing (as compared in my mind to trying to do an FFT). These are the questions I'm trying to figure out. If you've got any experience to provide in the matter, I'd really appreciate your insight. I'll try to keep an eye on this newsgroup but it's ont part of my daily routine, so if you email me, I have a more likely chance of getting it. I can be reached at mnorton@redwood.dn.hac.com.

'Got a design, written in verilog of about 1000 lines. Synopsys reports 3500 gates, at least when targeting the, not very usefull ASIC library that the university uses. My normal synthesis tool, Asyl+ doesn't report gate counts. For a variety of reasons, I'm trying to fit this to an Altera Flext 10K10 FPGA. Should be easy, right? 3500 gate design, 10000 gate part. But it doesn't fit. I could understand possibly having routing problems but I'm running out of logic cells: 610 vs the 565 cell capacity of the 10k10. On the "8000 gate" Motorolla MPA1034, the design takes up 70% of the capacity. (won't route but I think that's just because synthesis isn't using the clock network) Any ideas on what could be causing this area explosion?

Thank you. > > Email: jangomez@unex.es > > URL: http://maxwell.unex.es/CALD Sure, I've worked with quite a number. Which is best really depends on the application and on who you ask. Generally speaking, you will probably want some local fast SRAM associated with each FPGA in the system. In many cases access to two banks of SRAM is desirable. You need to study the types of problems your system will be solving and slant the architecture to fit the problem at hand. The structure of the interconnect is the biggest variable (ie lattice vs. linear pipeline). There are several commercially available systems out there including ones by Virtual Computer, GigaOps and Annapolis Microsystems. Each has a different architecture that has it's own pluses and minuses. You might look at these systems to see if the architecture fits your needs before investing in your own design. -Ray Andraka, P.E.

Hello, I am interested how much area is spent in current FPGAs and CPLDs for routing. The block diagrams e.g. of lattice devices suggest that this is a reasonable amount. OK I know that the anti-fuse camp claims to have no area overhead for programmable interconnects at all. I am only interested in the area of the routing resources itself, not for the logic for configuring them. I have not yet seen die photographs of current CPLDs to estimate it. (ok on the databook and the FLEX8000 handbook are some kind of photographs). Some insider dares to answer?

There is another difference that I haven't seen mentioned in the recent discussion. Look at the ratio of logic to IO. FPGAs typically have more logic per IO pin than CPLDs. So FPGAs typically work better than CPLDs if your problem requires a lot of state that doesn't need to be connected to the outside world. A good example would be a few counters and a few comparators that make a few flags. I'd probably rough out the design in both technologies far enough to see which felt better. Beware, don't expect the same logic equations to work well in both cases. You want to bend things to take advantage of the available resources/features. I recently ported some logic from an FPGA to a CPLD. After I finished you would not quickly recognize them as the same design.Article: 4839

It's a lot safer to ride a plane than a car. That is a common misconception combined with an incorrect interpretation of statistics. Traveling a given DISTANCE by commercial airline is safer than traveling the same DISTANCE by car. Traveling for a given TIME on a commercial airline is likely to be more dangerous than traveling for the same time by car. Estimating exposure to risk for airline flyers has to be measured in deaths per people-mile to create a normalized statistic. This takes into account both the difference in speed and the difference in numbers of passengers.

For using a general programmer (i.e., you want the data in s-record format or some such), run Xilinx's makeprom software. There is a free utility you can get from Xilinx called PSPLIT (I believe--I haven't used it for a while) that takes the one large programming file and splits into N files (for however many PROMs are needed.) I found this extremely useful for my design with 9 XC17128s (changed to 5 XC17256s when they became available.) > >Thanks, >Andreas > If you have more questions, Xilinx tech help should be very supportive. I had problems initially with the 'D' parts that they assisted me in troubleshooting. (Remember: slow clocks does not necessarily mean soft edges! My long run for CCLK to all the parts was my problem that didn't show up with the old, slower parts.) Have fun. JasonArticle: 4842

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ This is the easiest, most honest way to legally break that bondage of debt and to share great wealth with others! Yes, Congress has passed a law making this perfectly legal. By doing the following, you are creating a service. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Hello! Take 5 - 10 minutes to read this and it WILL change your life!!!!!!!!! If you want to know how to make thousands of dollars quickly, legally, and with no catch, then keep reading. A little while back, I was browsing these newsgroups, just like you are now, and came across an article similar to this that said you could make thousands of dollars in weeks with only an initial investment of $5!!!!!! And I thought "Yeah right, what a scam", but like you (and you are reading this), I was curious. So I kept reading. The letter said to send $1 to each of the 5 names and addresses listed in the article, then to place my own name and address in the article at the bottom of the list (position #5) and post the article in at least 200 newsgroups (there are thousands). No catch, that was it. So, after thinking it over and talking to a few people first, I tried it. I figured what have I got to lose except 5 stamps and 5 bucks. Well, guess what.. within 7 days I started getting money in the mail! I was shocked!! I still figured it would end soon, and didn't give it another thought. But the money kept coming in, tripling in size and multiplying by THIRTEEN times the amount that I got the first week. In my first week I made about $20 - $30. But by the end of the second week, I had made a total of over $1,000.00 !!!!! In the third week, I had received over $13,000.00 and it's STILL growing. Let me explain how this works, and most importantly, WHY it does... **** The process is very simple, and it consists of 5 EASY steps: ******** STEP 1: Get 5 seperate pieces of paper and write your name and address along with the words "Please add me to your mailing list. You are currently # n (where n = 1 to 5 position on the list). This way, you are not just sending a dollar to someone, you are paying for a legitimate service. STEP 2: Get 5 one dollar bills, place one bill inside each of the five pieces of paper you wrote on, then fold each piece of paper so that the bill won't be seen through the envelope. You should now have five sealed envelopes. Each one has one dollar in it, folded inside the piece of paper. STEP 3: Mail the five envelopes to the following five addresses: 1. T. Johns, P.O. Box 16936, Jackson, MS 39236-6936 2. B. Pope, 650 Old Fannin Rd Box #D9, Jackson, MS 39208 3. J. Torok, 2647 SW 33rd Ave apt 811, Ocala, FL 34474 4. J. Campbell, 1040 C Winners Circle, Bowling Green, KY 42104 5. L. Brennan, 2605 NW Columbia, Lawton, OK 73505-6237 STEP 4: Using the above list, edit it by DELETING name #1 on the list. Put yourself at position #5. Move the other names up (5 becoming 4, 4 becoming 3 etc.) The longer your name is on the list the more money you make, and #5 will be on the list the longest!!! That's where you want to be!!! STEP 5: Post your edited article (with your name at position # 5) to at least 200 newsgroups (I use ALT.NET, which has about 26,000 of them!) I found that 200 will do quite nicely!! HOW TO POST YOUR EDITED ARTICLE If you have Netscape 3.0, do the following EXACTLY: Click on any newsgroup like normal, Then click on "TO NEWS", which is on the far left when you're in the newsgroups page. This will bring up a box to type a message in. Leave the newsgroup box like it is, change the subject box to something flashy, like, "NEED CASH $$$ READ HERE" or "FAST CASH"!!! Tab once and you should be ready to type. Now retype(only once) this WHOLE article WORD FOR WORD, except to insert your name at #5 and to remove #1 off the list, plus any small changes you think you need to make. Keep almost all of it the SAME! When you're done typing the whole article, click on FILE in the BOX right above SEND, not where it says netscape news on the first box. Click on SAVE AS when you're under file. SAVE your article as a text file to either your A: or C: drive. DO NOT SEND OR POST YOUR ARTICLE UNTIL YOU DO THIS!! Once SAVED continue on. If you still have all of your text, send or post to this newsgroup now, just by clicking send. Now post this article to all 200 newsgroups. OK, click on any newsgroup, then click on "TO NEWS", againin the top left corner. Leave the NEWSGROUPS Box alone again, put a flashy subject title in the SUBJECT box. This will result in a new box coming up. Click on ATTACH FILE, then find the article that you saved. Then click once on the file and then click OPEN. Next, click on OK. If you did this right, you should see your filename in the attachments box, and it will be shaded green. IF YOU USE EXPLORER, IT'S JUST AS EASY Holding down the left mouse button, highlight this article. Then press the "Ctrl" key and the "C" key at the same time to copy this article. Then print this article for your records to have the names of those you will be sending $1 bills to. Next go to the newsgroups and press "post an article", a window will open. Type in your headline in the subject area and then click in the window below it. press "Ctrl" and "V" and the article will be placed in the window. If you want to edit the article, do so and highlight it and copy it again. Now everytime you post the article in a newsgroup, all you have to do is repeat the "Ctrl" and "V" combo and post it. That's it. Each time you do this, all you have to do is type in the name of a different newsgroup (I do ten at a time)so that you end up posting to at least 200 different newsgroups. It only takes my computer-illiterate wife about 30 seconds per post, doing 5 newsgroups per post. And the more you post, the more money you will make!!! And once you see how easy this is, I promise you that you will become efficient at this program!!! You are now in the mail order business, and you will start receiving your $1 envelopes from various people all over the world within days. You may want to rent a P.O. Box because of all the mail. If you wish to remain anonymous, you can invent a name, such as "manager" or whatever. Just make sure all of the addresses are CORRECT please.!!!!! The Internet has grown tremendously. It doubles in size every 4 months!! Literally THOUSANDS of people read newsgroups EVERY DAY!!! Out of 200 postings, let's say I only receive 5 replies, which is actually VERY LOW. So I made $5 with my name at position #5. Now each person who just sent me $1 makes, say only 200 postings, now with your name at #4, which is a total of 1000 postings, not including yours. 50 people send you $1 now. That's $50 you just made!! Now your 50 new agents each post 200 with your name at position #3, or 10,000 postings (50 X 200). The average return is 500, at $1 each, that's $500. They make 200 postings each, which is 5,000 returns, at $1 each is $5,000!!!!!! And finally, 5,000 people make 200 postings each, with your name at #1. You get a return of $50,000 before your name drops off the list. And that's if eveyone only does 200 posings, and if only 5 people respond!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! When your name is no longer on the list, you just take the latest posting that is appearing in the newsgroups, and send out another $5 to the people on it, putting your name at #5 again. And start posting again. The thing to remember is : THOUSANDS OF PEOPLE ALL OVER THE WORLD ARE JOINING THE INTERNET AND READING THESE ARTICLES EVERY DAY, JUST LIKE YOU ARE RIGHT NOW. So are you willing to risk $5 for a chance to CHANGE your financial future for the rest of your life? Believe me it works. People have said, "What if the plan is played out and no one sends any money?" So what! What are the chances of that happening, when there are tons of HONEST, NEW users and people who are joining the Internet and newsgroups daily and are willing to give it a try? Estimates are at 1,000,000 per DAY worldwide, with many of those joining newsgroups!! You might even be new, and you are reading this right now, correct? REMEMBER, play FAIRLY and HONESTLY and this will work, I promise you. You just have to be honest. Keep a list of who sends you $1, and keep an eye on the newsgroups, to make sure everyone is playing fair. REMEMBER HONESTY IS THE BEST POLICY. YOU DON'T NEED TO CHEAT THE BASIC IDEA TO MAKE A LOT OF MONEY!!! GOOD LUCK TO ALL, AND PLEASE PLAY FAIRLY THE FIRST TIME, AND YOU WILL REAP THE REWARDS FROM THIS . . . TONS OF X-TRA CASH!!!!! ! ! ! ! ********* By the way, if you trt to deceive people by posting the messages with your name on the list and not sending the money to the people already on the list, you will not get much. A guy I talked to did that, and he only made $150, and that's after 7 or 8 weeks. The he wised up. Who is gonna help you if they don't see that you are honestly doing your part, by sending them each $1 like they did before you?? Then he sent the $5 out , and the people ADDED HIM TO THEIR LISTS, and in 4 to 5 weeks he made over 10,000 dollars. _____________________________________________________________________ THIS IS THE FAIREST AND MOST HONEST METHOD I HAVE EVER SEEN TO MAKE HUGE CASH BY INVESTING ONLY A LITTLE TIME! ! IF YOU ARE REALLY SERIOUS ABOUT CHANGING YOUR LIFE AND BECOMING DEBT FREE, DO IT, DO IT RIGHT NOW, AND IN A MONTH ALL OF YOUR DREAMS CAN COME TRUE! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !Article: 4848

I would be particularly interested in objective benchmarks for all the traditional parameters (routability, etc.) as well as non-traditional, but otherwise equally useful metrics such as ease-of-use of tools, changeability, etc. Thanks, Tom JonesArticle: 4849

Though I suppose, it means we may still have a choice of operating system after we've lost the choice of architecture. ---- "..very sad life. Probably have very sad death.
