HOW TO ATTRACT GIRLS INSTANTLY....Secrets to instant sex appeal PURE INSTINCT PHEROMONE ATTRACTANT FOR MEN WILL GIVE YOU AN UNFAIR ADVANTAGE WITH WOMEN GUARANTEED (or your money back)! Everyone knows that some men (a tiny minority) are able to instantly attract women. It used to be known as "animal magnetism". Scientists now say this natural attraction is due to pheromones - body smells that are not consciously detected, but that effect the behavior of others towards the person giving off these chemical signals. It's natures way of attracting the opposite sex. Scientists have now isolated and synthesized two natural Attractants- androstenol and androstenone pheromone. Carefully controlled experiments show they work and have been widely reported on television and in both the British and international press. Androstenone pheromone has been successfully tested on BBC TV's "TOMORROWS WORLD" and by Desmond Morris (Author of "The Naked Ape" and "Manwatching" and renowned human behaviorist) on BBC TV's "Friday Night... Saturday Morning." New improved formula PURE INSTINCT from ICT Research Technology contains both ANDROSTENOL and ANDROSTENONE pheromone and produces and undetectable scent that subconsciously attracts women to the wearer. PURE INSTINCT is the world's number one selling and the most concentrated (5 - 7 x normal active strength) pheromone spray for men - don't be misled by cheaper (or more expensive) imitations. WHAT THE PRESS SAY: * Lowell Ponte, a former consultant on exotic weapons and a Readers Digest science writer, said in an interview that "use of the recently discovered chemical Androstenone should be banned. Congress should pass a law making it a crime to use this chemical to influence voters by making politicians appear more lovable. - The San Francisco Chronicle - * "The stuff attracts women like you wouldn't believe" - Colorado Telegraph * "And now this pheromone has been marketed, we've tested it - and good grief it works" - Koave * "pheromones influence human behavior in a subtle way. Women are attracted to the smell" - The Daily Telegraph * "Pure Instinct is likely to produce a state of sexual excitement or arousal" - Men Only (Vol. #44 No. 4) Much of our sales of PURE INSTINCT are reorders from existing users, reports confirm success. "PURE INSTINCT really does seem to work! The most dramatic instances have occurred when wearing it at discos. Girls just drift towards me and start flirting." -DT Cardiff "I Knew PURE INSTINCT wasn't a gimmick when one of the girls at work, quite out of character, started to seduce me when we were alone in the office." -SD Nottingham PURE INSTINCT comes in a discreet 15ml pocket roll on container with full instructions, Ideal for any man who wants to join that lucky few who have more than their fair share of sex appeal. 30 DAY MONEY BACK GUARANTEE If you are not 100% delighted with the results from using PURE INSTINCT simply return remainder within 30 days for a full refund- No questions asked!

As far as back annotation usually (especially for Period), the timing should match. A few questions: 1. do you have all of the patches installed for 9.1 (i.e. patches a-f)? They have also released orca foundry 9.1.5 which is the latest and you do not need to install any patches. 2. Does your sdf file look correct? For example are other delay numbers correct or is everything way off? Look into the sdf file and see if many of the entries are 0's. 3. What simulation tool are you using? If there is any problem with the sdf file, the tool could be defaulting to default values. I have created numerous Orca designs and have back annotated to vhdl and usually the timing is very close. One thing that I have found is that if there is as difference, the trace reports are usually more accurate. Regards, TonyArticle: 7907
Has anyone successfully used a FLASH memory to configure Altera 10K parts? I am about to look into this, for the purpose of having non-volatile ISP in my product, for field upgradeability. On boards containing Xilinx, I believe that this will work rather smoothly, as they have an inherent parallel programming mode that works fine with EPROMs, so I just need a FLASH that emulates a conventional EPROM for reading (although, I must somehow still provide write access to the local PCI port). Anyway, just seemed like a good thread to ask this question. I would appreciate copying any replies to sbierly@sed.stel.com, since I can't read this group at work.

Oliver, If by modeling a processor based structure you mean implementing a processor (or processor like structure), yes I have. The first was in an 81500 , (long story about part choice - determined by out of date tools at company)., anyway, that design was a 10 MIP microcoded 16 bit processor and peripherals used to implement a digital trap-drive motor controller (40khz voltage and current loops with a 16 bit 4 quadrant multiplier, motor commutation, etc.). My current processor (24 Bit) is more general purpose and significantly faster (approx. 40 MIPS). I expect it to fit completely (including registers) into approx. 1/2 - 2/3 of a 10K20. Should be interesting, as I am considering implementing hardware supported data and program frame management. BTW, the Altera parts (10Kxx) are a very good match for the processor architecture I am designing, also, I recently (last week) purchased a constellation board from Nova engineering ( www.mova-eng.com ) with a 10K50V-3 on it for hardware modeling - nice board, good service, good delivery, not too bad a price, all in all, a very positive experience.

Hi, everyone: I need your help. I use ALTERA's FPGA to design a controller. The first time, I assign the time for some pins, and fit successfully. But the pins are not distributed as I wanted. When I assign the pins location, I found it cann't fit or cann't get the specified time. I want to compile a design at first, when it success, back_annonate the design, but I find if I back_annonate the disign, I cann't modify the pins and logic cells in Floorpan editor. I think it can work, I don't know the answer, who can tell me. If you have used ALTERA's FPGA, please give me some advices. Thanx Songsong.Article: 7919
VIUF International Users' Forum (VIUF) Fall 1998 CALL FOR TOPICS "Idea Factory: VHDL for Power Users" Over the past ten years, the EDA Industry has seen VHDL and some of its satellite standards evolve from infancy to maturity. The VHDL International Users' Forum (VIUF) has contributed significantly toward the introduction of VHDL and its companion standards to the user community. However, feedback from users has indicated that VIUF must do more to address the needs of the "experienced" user. In light of this, the Steering Committee for VIUF Fall 1998 has chosen to devote the majority of its focus to the needs of experienced users and the practical, real-world applications of VHDL. (Of course, we promise not to forget the novice user in our plans, so don't worry if you're just getting started using VHDL.) The format of the Fall Forum is also changing, i.e., in addition to providing a forum for instruction and presentation of the latest information available concerning the practical application of VHDL, the Steering Committee is working on a format for VIUF Fall 1998 that will promote information interchange among the attendees. We also hope to offer you more, in a tangible sense, than just a copy fo the "Proceedings" to take home with you. However, in order to better meet your needs, we need your help. In short, we need to know which topics related to VHDL and its companion standards are of the greatest interest to you. The VIUF Fall 1998 Steering Committee invites you to submit one or more topics that are of interest to you and/or your colleagues. Please send your suggestions to the Program Chair, Peter Ashenden, via electronic mail to: petera@ececs.uc.edu or by regular mail to: Peter Ashenden Dept ECECS, PO Box 210030 University of Cincinnati Cincinnati, OH 45221-0030 USA Phone: (513) 556 4756 Fax: (513) 556 7326 Submit your suggestions by no later than December 1, 1997. Subsequent to receiving your suggestions, the official "Call for Participation" will be distributed later this year. This is your forum, so please assist us in serving you better by offering your suggestions. Thanks in advance for your help.Article: 7920

Two possibilities: 1) Look-ahead carry would be helpful for D flip-flops. Use a macrocell here and there to "gather" carry information from previous counter stages, to tell the next stage when to count. You use a few more macrocells than actual counting bits, but it will stay within the GLB p-term limits of the ispLSI1016. 2) Also, use the hard-XOR gates available on the registers in a GLB to create a psuedo-toggle flop. In ABEL-HDL, this is done by specifying discrete XOR equations and declaring those registers as "istype XOR". -TBBArticle: 7922

Russell, What version of Max+plus II are you using to generate the pof file? I know in in the newester version, 8.1, the default POF file generated for 10k10, 10k20 and 10k30 is for EPC1441, not EPC1. You have to perform combine programming file to covert it to EPC1 format.

The Atmel AT40K is pin compatible in that it can be used in a Xilinx socket (dedicated pin assignments are the same, xilinx configuration modes and protocol are supported). The internal architecture is quite different however. Which part is the better one really depends on the application. Atmel's pricing is very aggressive (I think it is about $40 for a 20K gate part in small quantities) so it is worth a look, especially in cost sensitive projects. -Ray Andraka, P.E.
