Hello David, The test case you provided to the hotline has been investigated and it was found that the I/O registers all had IOB=FALSE attributes on them. This mapping directive takes precedence over use of the "-pr b" command line switch. This explains why none of the registers were mapped to IOBs. The 2.1i SP6 behavior was also checked and found to be the same. The 4K mapper does not support the IOB attribute which explains why the registers were mapped to IOBs when you targeted a Spartan device (instead of Spartan-II). I suggest that you investigate the source of the IOB=FALSE attributes in the front end tool. BTW, there was an I/O register packing bug in the original release of 3.1i that affected certain configurations. It was fixed in the first 3.1i service pack.

Here's part of a short message that someone from Xilinx sent me just minutes ago: The test case you provided to the hotline has been investigated and it was found that the I/O registers all had IOB=FALSE attributes on them. This mapping directive takes precedence over use of the "-pr b" command line switch. This explains why none of the registers were mapped to IOBs. The "-pr b" mentioned is the same thing as the option you mentioned, just the command line version of that option. I looked at the EDIF netlist and it sure does set the IOB attribute to false. The next question is, Why? I didn't tell it to be false. I guess there is more detective work to be done. The guy from Xilinx also said that this is unrelated to the other IOB bug that was fixed in SP2 (paraphrased). David Kessner davidk@free-ip.comArticle: 25002

I use the same (or similar) OS, but I am using Netscape for reading the newsgroups. Over the generations it seems that they give you less and less control over the display formatting. I though I used to have control over the width of the lines that I sent. Now at the top of my window I can see the tick mark showing the width of the text to be sent. But I have no control over where it is. As far as I can tell, I have no control at all over the display of text line widths. But I have found that I can read non-wrapped lines if I start a reply message. The echoed text will then be wrapped in the edit window. :-) -- Rick Collins rick.collins@XYarius.com Ignore the reply address. To email me use the above address with the XY removed.

Netscape 4.7. I have not found a way other than to open a reply. The edit window shows the lines wrapped. Usually the unwrapped lines are not so long that they can't be read easily. But this post had quite long lines. What is the standard (if there is such a thing for wrapping lines in messages sent to the newsgroups?

Opps, I took a harder look at the preferences and found that it will wrap lines on messages. I think I turned if off because I was getting a lot of messages that were wrapping one word from a line onto the next line. This is as annoying as the really long lines. I also found the control for the outgoing line wrapping width... :-) Andy Peters wrote: > > rickman wrote: > > > > I don't mean to nitpick, but I would like to request that you do > > something with your posting software to wrap your lines at some > > reasonable length such as 70 or 80 characters.

It seems that FPGA Express, in this version at least, defaults to IOB=false. In the previous version it would default to "none". This is the source of my troubles. Changing it to TRUE fixes everything. Now my problem is how to set it to TRUE from a makefile and not the Xilinx Project Manager... David Kessner davidk@free-ip.comArticle: 25009

A credit report? I've heard places use this, but I can't imagine to what legitimate use it would be put. Employability should have nothing to do with finances. If an interviewee has credit problems, so what? Of course, illegitimate uses exist - making sure you only hire managers of the correct social class, etc. Same for generic "background" information. It's nice for keeping the old-boy network alive. And I can't believe people still think drug testing is reliable.Article: 25010

Yes, but the odds of a company that is draconic about its treatement of individuals creating havoc in someone's life is much larger than that of a meteorite falling on one's head. Your example is inappropriate, especially from a statistical POV. In reading your various post, you seem to take an apathetic attitude towards what should be a relationship of mututal respect. At the start of any relationship, a healthy amount of doubt should be used, but some companies go over the top. Basically, you have a lot of big words and windy sentences that leave me with the impression that you are saying: "Why should I bother to care about an NDA or any other invasive processes that a company forces upon me since they won't be used to my detriment now?" If you can't envisage a future situation wherein these overbearing actions can result in bad experiences for you, whether through stupidity or malice on the other's part, then you might as well stop arguing with someone like Jon who's apparently had something like that happen to him. ____________________________________________________ Paul Tiseo, Intermediate Systems Programmer Birdsall 3, Mayo Clinic Jacksonville 4500 San Pablo Rd, FL, 32224 tiseo.paul@mayo.edu -- (904) 953-8254Article: 25011

Hmm, I remember having to sign something similar for my current job. I had forgotten about it. I remember that it took quite long time to get my official offer (I had authorized this after the unofficial offer). It turns out, the investigating company could not determine that I had actually gone to college!! Pretty inept it seems. The employer finally decided to stop waiting for a reply and hired me anyway. When I signed it, I was told it was for verifying the facts in my resume and application; and I seem to recall that it didn't have a blanket "investigate everything" feel to it. But what do you do? Don't sign, no job; versus sign and some bureaucratic HR person I will never see is happy. Or argue with a lawyer to change the terms, and start off my first day with an earned reputation of being a trouble maker and a risk. On the other hand, from my view, none of these things are near as bad as an employment agreement that says you can be fired "at will" with no reason given. Yeah, they're just extra flexibility for the company (ie, more power for them), but still... What's worse, a VP who dislikes you who then goes out and gets a credit report to justify firing you, or the same VP firing who doesn't need any excuse at all? The tricky part is that if you don't get the job, or get fired, it may be because of information the company is not legally allowed to use in its decision making; yet how do you find that out or prove it? (beware of arbitration agreements that prevent fair legal recourse) > 2) they did not acknowledge that a drug test can be wrong. It can be > wrong for a large number of reasons; poppy seeds (yes that is true), > prescription drugs, and many "medicinal" herbs sold in health food > stores. Of course, what happens is that a DOD contractor has to prove they are a drug free workplace. Doing that in practice is extremely difficult. How do you prove it? The cheap and hassle-free way (for them) is to do drug testing. Any other solution is an enormous burden for them. Thus, when a single person, or a small minority, object to this testing, it doesn't matter. It's better that they don't hire this person than having to change all their policies and institute a *real* drug-free workplace policy. And of course they can't make exceptions, because they told the government that they wouldn't. Thus, no exceptions. And of course no recourse, because the policy implementers are just bureaucrats you'll never see, and your hiring manager will never see. However, I did work at Lockheed without having a drug test, even though there was a company wide drug testing policy for new hires. Apparently the nurse was gone the day I had my physical (that was *wierd*, what were they going to do, not hire me because I wasn't healthy?); so they skipped the drug test that day, and they never called back. > 3) to make sure that I could not dispute the result of the test it was > given at the interview so that if it was failed they would simply not > make an offer. You would never know that you failed the drug test. I find it disturbing that you typically never know why you didn't get a job. After several months of a job search (ultimately, eleven months), I was disturbed to be told finally by an employer that I didn't get the job because "we didn't feel you really wanted the job". It came out that my body language, speaking style, and overall shy/formal attitude was working against me. If I had known this much earlier on... After I started consciously remembering to be more animated, and "acting" during the interview instead of being myself, I started getting much better responses... Of course, there were still the "we do want to hire you, but we just had our budgets slashed"...Article: 25012

Jon does look like he needs a break, how about if I argue with you. Have you had the experience--not envisaged (imagined), as we may envisage quite at odds with the facts--of some unethical behavior by an employer in or closely related to the issues we are discussing? At the moment we have various vague claims that they happen, but factual details (as in the name of the company involved, Jon) are conveniently missing. I think if we want to have an accurate statistical study, that we take care to have accurate, credible data with which to make a statistical assertion. Less accurate data, we cannot argue for much of anything, large or small. However, I am not seeing much hard data by the opposition, who should know since they are the opposition, that there is a large problem, hence I am concluding that the problem is small. I.e., if there are those who are earnestly looking and they do not find hard data, it is likely that the hard data is not there. No doubt, the previous has too many big words and windy sentences, so let us try the following. I give a small jar with a lid to a child and ask the child to go out into the yard and collect some ants in the jar. The child comes back and relates to me tales of strange and wondrous ants of innumerable number. And looking forward to seeing these curious ants for myself, I ask the child for the jar and upon seeing it, see that it is empty. Perhaps the child got carried away envision- ing ants and forgot to collect them, or perhaps if the child made any effort at all there were no ants to be found. Now against the general tone of my argument is an article on the front page of today's Los Angeles Times titled ``Courts Question Rules Barring Suits by Workers''. The article discusses two cases: one before the California Supreme Court and one before the U.S. Supreme Court. There are some juicy passages in that article that could be used for good effect against my position. It is likely there are web sources for this. I am quite sure there are a good number of interviewing and other employer practices that need to be opposed, but we need to oppose them accurately and effectively. I am not particularly against or for employers or employees. I am for capable action that solves problems well. These problems are not simple, and a lot of work can be done on them. Regards, Neil Nelson P.S.: There may be good arguments for not giving company names but some- one needs to make them.Article: 25015

Can we, please, stop this endless and boring discussion about fine legal points and paranoia of a few individuals that I mostly never met here before. This discussion really has no place in a newgroup about computer architecture fpga. I just don't know anybody who is interested in this subject. As I said before, an employer who asks for an NDA in a first-level interview should have his head examined... For a contractor this may be a different issue, but I trust that our contractor friends are savvy enough to handle this. Of course, this is an unmoderated newsgroup, and the story can go on forever.

David, In the make file you can use "set_pad_register" constraint to use IOB registers. The syntax for using this constraint is set_pad_register TRUE net_name You can do a "man" on this constraint in FE_SHELL to get all the details. Hope this helps. Vikram Xilinx ApplicationsArticle: 25018

that goes to make up the knowledge behind it.

As I said, I am just 3 miles from an establishment where you will sign an
NDA just to visit them (and to break the agreement is at this place is
considered a treasonable act - carrying very stiff penalties). Their
wording, though, is very fair to both parties.

Article: 25020NO LIE!! MAKE LOT$ OF MONEY RISK FREE!! ALL YOU NEED IS READ.. Message posted by TRYA ( <mailto:>) on Friday, June 25 at 02:00 PM EDT Message: MAKE LOTS OF MONEY Thursday, 17-Jun-1999 16:12:14 205.188.197.178 writes: THIS TIP WILL BLOW YOU AWAY******** I found this on a bulletin board and decided to try it. A little while back, I was browsing through newsgroups, just like you are now, and came across an article similar to this that said you could make thousands of dollars within weeks with only an initial investment of $6.00! So I thought, "Yeah right, this must be a scam", but like most of us, I was curious, so I kept reading. Anyway, it said that you send $1.00 to each of the 6 names and address stated in the article. You then place your own name and address in the bottom of the list at #6, 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 thought about trying it. I figured: "what have I got to lose except 6 stamps and $6.00, right? "Then I invested the measly $6.00, Well GUESS WHAT!?...within 7 days, I started getting money in the mail! I was shocked! I figured it would end soon, but the money just kept coming in. In my first week, I made about $25.00. By the end of the second week, I had made a total of over $1000.00! In the third week, I had over $10,000.00 and it's still growing. This is now my fourth week, I have made a total of just over $42,000.00, and it's still coming in rapidly. It's certainly worth $6.00, and 6 stamps, I have spent more than that on the lottery!! Let me tell you how this works and most importantly, WHY it works. Also, make sure you print a copy of this article NOW, so you Can get the information off of it as you need it. I promise you that if you follow the directions exactly, that you will start making more money than you thought possible by doing something so easy! Suggestion: Read this entire message carefully! (Print it out or download it.) Follow the simple directions and watch the money come in! It's easy. It's legal. And, our investment is only $6.00 (Plus postage) IMPORTANT: This is not a rip-off, it is not indecent; it is not illegal; and it is 99% no risk - it really works! If all of the Following instructions are adhered to, you will receive extraordinary dividends. PLEASE NOTE: Please follow these directions EXACTLY, and $50,000.00 or more can be yours in 20 to 60 days. This program remains successful because of the honesty and integrity of the participants. Please continue its success by carefully adhering to the instructions. You will now become part of the Mail Order business. In this business, your product is not solid and tangible, it's a service. You are in the business of developing Mailing Lists. Many large corporations are happy to pay big Bucks for quality lists. However, the money made from the Mailing lists is secondary to the income which is made from People like you and me asking to be included in that list. Here are the 4 easy steps to success: STEP 1: Get 6 separate pieces of paper and write the following on each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST." Now get 6 US $1.00 bills and place ONE inside EACH of the 6 pieces of paper so the bill will not be seen through the envelope (to prevent (thievery). Next, place one paper in each of the envelopes and seal them. You should now have 6 sealed envelopes, each with a piece of paper stating the above phrase, your name and address, and a $1.00 bill. What you are doing is creating a service. THIS IS ABSOLUTELY LEGAL! You are requesting a legitimate service and you are paying for it! Like most of us I was a little skeptical and a little worried about the legal aspects of it all. So I checked it out with the U.S. Post Office 1-800-725-2161) and they confirmed that it is indeed legal. Mail the 6 envelopes to the following address: (#1) Authur Smith 4118 Linnfield Houston, TX 77016(#2) Micheal Kayman 1875 43RD Ave SF, CA 94122 (#3) Rich White 216 Old Timberlake Rd. Apt 305 Lynchburg VA 2450(#4) Joey Knowles RT.1 Box 358 Montgomery AL, 36105(#5) Satryo Winanto 1825 County Rd F East White Bear Lake, MN 55110(#5)Randy Bowoo 962 Trojan Ave San Leandro, CA 94579. STEP 2: Now take the #1 name off the list that you see above, move The other names up (6 becomes 5, 5 becomes 4, etc...) and Add YOUR Name as number 6 on the list. STEP 3: Change anything you need to, but try to keep this article as close to original as possible. Now, post your amended article to at least 200 newsgroups. (I think there are close to 24,000 groups) All you need is 200, but remember, the more you post, the more money YOU make! You won't get very much unless you post like crazy. =) This is perfectly legal! If you have any doubts, refer to Title 18 Sec. 1302 & 1341 of the Postal lottery laws. Keep a copy of these steps for yourself and, whenever you need money, you can use it again, and again. PLEASE REMEMBER that this program remains successful because of the honesty and integrity of the participants and by their carefully adhering to the directions. Look at it this way. If you are of integrity, the program will continue and the money that so many others have received will come your way. NOTE: You may want to retain every name and address sent to you, either on a computer or hard copy and keep the notes people send you. This VERIFIES that you are truly providing a service. (Also, it might be a good idea to wrap the $1 bill in dark paper to reduce the risk of mail theft.) So, as each post is downloaded and the directions carefully followed, six members will be reimbursed for their participation as a List Developer with one dollar each. Your name will move up the list geometrically so that when your name reaches the #1 position you will be receiving thousands of dollars in CASH!!! What an opportunity for only $6.00 ($1.00 for each of the first six people listed above) Send it now, add your own name to the list and you're in business! -DIRECTIONS----FOR HOW TO POST TO NEWSGROUPS---------Step1) You do not need to re-type this entire letter to do your own posting. Simply put your cursor at the beginning of this letter, drag your cursor to the bottom of this document, and select 'copy' from the edit menu.

Step 4) Use Netscape or Internet explorer and try searching For various newsgroups (on-line forums, message boards, chat sites, discussions.) Step 5) Visit these message boards and post this article as a new message by highlighting the text of this letter and selecting paste from the edit menu. Fill in the Subject, which will be the header that everyone sees as they Scroll through the list of postings, in a particular group. Click the post message button. You're done with your first one! Congratulations:) THAT'S IT! All you have to do is Jump to different newsgroups and post away, after you get the hang of it, it will take about 30 seconds for each newsgroup! **REMEMBER, THE MORE NEWSGROUPS YOU POST IN, THE MORE MONEY YOU WILL MAKE! BUT : YOU HAVE TO POST A MINIMUM OF 200** That's it! You will Begin receiving money from around the world within days! You may eventually want to rent a P.O. Box due to the large amount of mail you will receive. If you wish to stay anonymous, you can invent a name to use, as long as the postman will deliver it. **JUST MAKE SURE ALL THE ADDRESSES ARE CORRECT. **Now, each of the 5 persons who just sent me $1.00 make the MINIMUM 200 postings, each with my name at #5 and only 5 persons respond to each of the original 5, that is another $25.00 for me, now those 25 each make 200 MINIMUM posts with my name at #4 and only 5 replies each, I will bring in an additional $125.00! Now, those 125 persons turn around and post the MINIMUM 200 with my name at #3 and only receive 5 replies each, I will make an additional $625.00! OK, now here is the fun part, each of those 625 persons post a MINIMUM 200 letters with my name at #2 and they each only receive 5 replies, that just made me $3,125.00!!!Those 3,125 persons will all deliver this message to 200 newsgroups with my name at #1 and if still 5 persons per 200 newsgroups react I will receive $15,625.00! With an original investment of only $6.00! AMAZING! When your name is no longer on the list, you just take the latest postings in the newsgroups, and send out another $6.00 to names on the list, putting your name at number 6 again. And start posting again. The thing to remember is: do you realize that thousands of people all over the world are joining the internet and reading these articles everyday?, JUST LIKE YOU are now!! So, can you afford $6.00 and see if it really works?? I think so... People have said, "what if the plan is played out and no one sends you the money? So what! What are the chances of that happening when there are tons of new honest users and new honest people who are joining the internet and newsgroups everyday and are willing to give it a try? Estimates are at 20,000 to 50,000 new users, everyday, with thousands of those joining the actual internet. REMEMBER, play FAIRLY and HONESTLY and this will really work. The possibilities can be endless...You will never know, unless you give it a try... otherwise, it will always be "what if"... "GOOD LUCK" =)Article: 25021

I don't recall the manufacturer's name off hand but I can look it up. I'm going to try some similar sockets for my current prototypes (different project) with a 0.8 mm pitch BGA. They're from Loranger (www.loranger.com). The socket is attached to the PCB by four screws, where the sockets pads are tiny springs that will make contact to the PCB pads. Not really press fit though, as there is no hole in the pads (unless you'll need a micro-via in the center to break out the signals on another layer) Don't have any experience on the reliability yet, but I can recommend Loranger otherwise. Sockets was delivered in 3 weeks and their price was quite good compared to others. > > For the case of the BGA560, was the socket or the package out of spec? Or were > the specs not fully consistent? The fault was in the socket. As this was 1+ year ago, I got units from very early production. After talking to the socket vendor, they found out that they had a bit larger shrinkage in the plastic molding process than expected. Should thus probably be ok now..... Loranger on the other hand, required a mechanical sample of the package when ordering to be sure that it would fit. Worked OK in my case as I had dummies, but could be less attractive if you're using an expensive chip that's not been used before. Wonder if FPGA vendors also can provide mechanical dummies?? Guess Peter would recommend buying the smallest package compatible device.... ;-) Regards, - OlafArticle: 25022
In a Xilinx application note, it is said that Virtex series have a column oriented partial reconfiguration feature. Does that mean that configuration data is shifted column by column until it reaches the desired column. Does that mean that if you wanna dynamically reconfigure a particular logic in Column 'N', you have to keep all 'N-1' columns that come before column N, empty???Article: 25023
Basically no. It is column replacement rather than shift. See XAPP138 & 151 which explain this in some detail.

Sure, but my assertion was that you are *appear* to be minimizing the actual *and* potential harm done by companies that do just what many are discussing in this thread. Comparisons to meteorites do not hide the fact that, unless there is an equal and opposing force to corporate mass paranoia and subsequent measures, that we could potentially suffer much more than some of us already do. It really was just my impression of your tone that I was relating, not a statement on the accuracy of inaccuracy of your statements. [ant-collecting example] > upon seeing it, see that it is empty. Perhaps the child got carried away > envisioning ants and forgot to collect them, or perhaps if the child made > any effort at all there were no ants to be found. I see what you are getting at and agree. People in newsgroup and USENET in general simply might not have the right "jar" to be collecting the "ants". :) ____________________________________________________ Paul Tiseo, Intermediate Systems Programmer Birdsall 3, Mayo Clinic Jacksonville 4500 San Pablo Rd, FL, 32224 tiseo.paul@mayo.edu -- (904) 953-8254
