I'm looking for documentation on the Library of Parameterized Models (LPM) standard. Network resources and examples would be even better. Has anybody built a VHDL version of LPM? Would a VITAL compliant library be useful to the FPGA community? Thanks for your input. Jose De Castro.Article: 553

I would like to know if you can use the Orcad output from Protel for Windows to feed the Xilinx software. A friend who called Xilinx was told that only Orcad STB-386+ (or something like that) would work properly and that other versions of the Orcad software don't work. This led me to question whether or not the Protel for Windows Orcad output would work. Since I already own Protel, I didn't want to have to buy Orcad and learn yet another user interface.

Thanks in advance No reason it wont work, the file is read from the disk, no storage in the cable. A quick testif you have a board with one 4010 on it woul be to gen up a ROM image with 5 copies of the config file for the 4010 an try loading that. If that loads almost for sure the string of 5 will work. ( May complain about done bit early, point is to see if it can read the file ) Martin Moelle mmoeller@delphi.comArticle: 558

The XC4000 must be the lead device, and the XC3000 part should be in serial daisy chain mode. The differences in framing codes does not effect the lead device (the XC4000), as it only looks at the bits at the beginning that are for it. When it is full, it starts passing the following bits (for the XC3000) from din to dout, and does not look at the bits. After the XC4000 is is full, and passing data to down-stream chips, the only thing it is still doing is counting bits waiting to go done. There should be only 1 header in the file, with the lengthcount field set to the sum of the two bitstream lengths. The makeprom program can do this for you. All the best Philip FreidinArticle: 559

Last night when I was channel surfing on the TV, I caught a quick snippet of the PBS Nightly Business Report that was talking about big stock gainers & losers for the day. The top NASDAQ loser was ViewLogic; it went from $18.50 down to $9.75 (a 47% drop) in *one* day. That's pretty dramatic for one day's trading. What's up?

Investor's Business Daily has a front page item about it today (04 Jan), including an "explanation" of the stock price tumble. Have a look.Article: 563
According to the news wires, fourth quarter earnings will be less than expected, but not by much. Also a lawsuit by stockholders has been filed with a complaint that insiders have been selling large amounts of stock recently before the drop. In my opinion, Viewlogic was over bought, and selling at a big premium, but now at 9 1/2, it may be a good buy. Fourth quarter earnings will be released the third week of January.Article: 564

The plunge in Viewlogic was due to the usual, earnings were less than projected. Wall Street doesn't like surprises. Viewlogic attributed the change due to the fact that sales of HDL products are doing better than expected, at the expense of their schematic-based products. This product change over is effecting their cash flow more than they thought. Also they could not sustain their rapid growth forever.

If Protel has .xnf output there is a good chance that they also have the libraire converted. Xnf without the libraries and macros would not meanmuch and if they are Orcad comaptible it would not eb hard for them to do. If they do have the libaries and .xnf you would simply feed the .xnf into the Xilixn tool chain as usual. The .pin is now the .inf format, .pin was the earlier Xilinx version that used Dataio net list format. The point is still valid though unless Protel has (or can directly use) the Xilinx library the effort would not be trivial. Martin Moeller mmoeller@delphi.comArticle: 568

I think you have to provide the schematic capture software for that as well. I wholeheartedly agree that it is not cost effective to buy the software to do one or two chips. There is another alternative you may not have considered. I run a consulting firm specializing in high performance FPGA design. One of the things we do is to convert existing designs into FPGA designs. The advantage of using a firm such as mine for someone like you is that we've already invested in the tools and have gained substantial experience using the tools and designing in the parts. My firm uses Viewlogic's Workview Plus along with the specific tools from each of the FPGA vendors.

FPD `95: Check out the WEB at http://www.ee.umanitoba.ca/Conferences/FPD/fpd.html ------------------------------------------------------------------------ The Third Canadian Workshop on Field-ProgrammableDevices: Technology, Tools and Applications May 29-June 1, 1995, Montreal, Quebec ADVANCE NOTICE AND CALL FOR PARTICIPATION ------------------------------------------------------------------------ The Ecole Polytechnique de Montreal and the Universite du Quebec a Montreal will host the Third Canadian Workshop on Field-Programmable Devices (FPD'95). The goal of this Workshop is to bring together workers from throughout Canada for a wide-ranging discussion on all forms of field-programmable devices and their applications. Discussion will focus on industrial applications, advanced CAD tools and systems, novel system architectures and educational experience. English will be used for discussions and the principal printed materials, but contributions can be submitted and presented in either English or French. SPECIFIC OBJECTIVES AND SCOPE OF THE WORKSHOP ------------------------------------------------------------------------ To continue to provide a forum for discussion on the design and application of FPGAs To provide an appropriate forum, both for those in industry and those in post-secondary education To allow manufacturers of field-programmable device software and hardware an opportunity to present their products to a specialized group To include a wide range of field-programmable devices such as interconnect components, analog arrays, etc. To increase the emphasis on designing at the system level, using synthesis to generate the circuit details These objectives will be implemented through: - ------------------------------------------------------------------------ Hands-on training - Tutorials and demonstrations - Industrial and academic case studies - Industry, university and educational paper sessions (lecture and/or poster formats) - A session on commercial opportunities and business implications SUBMISSION OF PAPERS ------------------------------------------------------------------------ Prospective participants are invited to submit one (1) copy of an extended summary to the Organizing Committee Chairs for review. The summary should be no more than four (4) pages in length, including title pages and figures. Submissions must be marked "FPD'95 WORKSHOP" and may be in hard copy or electronic format. Acceptable electronic formats are PostScript, FrameMaker and WordPerfect. Authors should indicate whether their preferred presentation format is lecture, poster or demonstration. If possible, authors should also provide an e-mail address to facilitate rapid communication. Authors of accepted papers (lecture, poster and demonstration) will be asked to prepare a camera-ready version for publication in the Workshop proceedings. As this is a Workshop emphasizing the exchange of ideas and research results, the material does not have to consist of unpublished results, but novelty is desirable. The referees will favour material that is of interest to industrial and/or university users of field-programmable devices. AUTHORS' SCHEDULE ------------------------------------------------------------------------ Submissions of extended summaries: Friday, January 27 (to Organizing Committee Chairs) Notification of acceptance: Friday, March 10 Final version of paper: Friday, April 21 Submissions should be addressed to: ------------------------------------------------------------------------ Prof. Mohamad Sawan (Co-Chair) Ecole Polytechnique de Montreal Department of Electrical and Computer Engineering P.O. Box 6079, Station centre-ville Montreal, (Quebec) H3C 3A7 CANADA Fax: (514) 340-4147 E-mail: sawan@vlsi.polymtl.ca. AREAS OF INTEREST ------------------------------------------------------------------------ It is expected that there will be a wide range of discussion topics because of the versatility of field-programmable device technology. Some suggested topic areas are: - Architecture and technology - Design and development tools - Industry case studies - Educators' experiences - Novel approaches to and utilizations of the technology - Design approaches - Business/commercial aspects of the technology - Entrepreneurial opportunities and support - System design issues - Synthesis opportunities for programmable devices - Partitioning across multiple FPGAs and/or interconnects. PAPER SESSIONS ------------------------------------------------------------------------ Researchers and industrial users are encouraged to show the results of their field-programmable device activities - the projects presented can be of an ongoing nature. Educators are welcome to present experiences with incorporating field-programmable devices into their curriculum. This is expected to be an active forum for the exchange of ideas for course and laboratory development. Industrial users are also encouraged to present case studies utilizing field-programmable devices in their particular environment. Papers describing how practical problems have been overcome are welcome. Manufacturers of field-programmable device software and hardware may also make presentations on the engineering characteristics of their software and/or devices. We are also soliciting presentations on the commercial and business aspects of this technology, including entrepreneurial issues. Examples of topics are: financial considerations of introducing field-programmable devices into the product life cycle; when to switch from field-programmable to mask-programmable gate arrays; etc. A combination of both lecture-style presentations and poster/demonstration sessions are planned for the workshop. The poster/demonstration sessions are provided for those applications where it makes more sense to present results using this format. Ecole Polytechnique may be able (reservation required) to lend workstations, PCs and other large equipment for use in demonstrations. Vendors of field-programmable-related products will also have a forum for demonstrating and promoting their products among workshop attendees. HANDS-ON SESSIONS ------------------------------------------------------------------------ During this Workshop, we anticipate hosting several hands-on sessions for a wide variety of users from novice to expert. Plans are being made to include tutorial sessions given by the major tool and device vendors.

Accommodation at the Radisson Hotel will be available at a special rate from the evening of May 28 (Sunday) until breakfast on June 2 (Friday), i.e. five nights. Additional nights and accommodation for non-participants can be arranged (see Registration Form). Montreal has numerous cultural and tourist attractions. Social programs will be organized for non-participants. OTHER USEFUL INFORMATION GENERAL: ------------------------------------------------------------------------ Montreal, a fusion of European style and the American way of life, is one of the loveliest cities in North America and is situated between the St-Lawrence River and Mount Royal. After Paris, Montreal is the second-largest French-speaking city in the world, with the advantage of offering services in English as well. TRANSPORTATION: Both airports offer convenient public transportation into downtown Montreal. The one-way shuttle bus fare is $8.50 Cdn. from Dorval and $13.50 from Mirabel. By taxi, the trip into town is about $25 from Dorval and $60 from Mirabel. In Montreal, there is an extensive bus and subway network (Montrealers call the subway the "Metro"), and a ticket for either costs $1.75. WEATHER: During the month of May, temperatures can vary quite a bit. During the day, they may reach 22 C, or drop to as low as 8 C. Evenings are generally cool (4 to 10 C).Article: 571

Thanks in advance > > Dave > Hi Dave, If you have one of the old parallel port download cables, then that definitly has no limit. The file simply seams to get read from disk as the bits are spat out the parallel port, one bit at a time. The only problem with that is that as the Xilinx devices have got faster, they have become more sensitive to glitches (and hence ringing) during download. The only big benifit with the XCHECKER is that the leads are short and ringing is not a problem. I like the old DOWNLOAD cable but after a lot of heartache & study, I have deciced that the only correct solution to the ringing problem is by adding an active buffer (74HC14) at the Xilinx end of the cable. Some old Xilinx manuals gave the schematic of the parallel download cable, so you could make one if you havn't got one handy (but watch out for ringing). I am asuming that you are not running long leads from the body of the xchecker head. Regards Michael.Article: 572
Request for Discussion (RFD) Newsgroup : comp.cad.viewlogic Status : unmoderated Distribution : Worldwide Summary : For discussion of Viewlogic's CAD software Proponent : Scott Murphy (scott@gordian.com) This is a formal Request For Discussion on the creation of an unmoderated newsgroup, comp.cad.viewlogic. This RFD has been posted in accordance with the Guidelines for Newsgroup Creation. Its language is based on previously submitted RFDs. The RFD is being cross-posted to the following relevant news groups: news.announce.newgroups comp.cad.synthesis comp.arch comp.arch.fpga comp.lang.verilog comp.lang.vhdl sci.electronics.cad CHARTER The comp.cad.viewlogic newsgroup will be open to discussion of the use of and any problems or conditions arising from the use of Viewlogic's Powerview and Pro series CAD software. Specific topics may include but are not limited to: Installation Design methodology Security Verification and Validation Bugs Vhdl Customization Product enhancement This group is not affiliated with Viewlogic, but it is hoped, that employees of Viewlogic will participate in the discussions. RATIONALE As Viewlogic has grown, it's software has evolved from a simple pc based schematic capture system into a full electronic design package. This growth has increased the difficulty in effectively using and maintaining that software. This forum will provide users of Viewlogic's software a place to solve problems and share ideas. It is hoped, that Viewlogic will use this group to aid their customers, and to solicite information about those customers needs. MAILING LISTS No know lists exist. FUTURE CALL FOR VOTES After a discussion period of 21-30 days, if there are no overwhelming objections to the proposed group, there will be a Call For Votes (CFV) posted to the same groups as this RFD. The voting period will be at least 21 days. If the group passes by receiving 100 more YES votes than NO votes, and (at least) twice as many YES votes as NO votes, it will be created. -- __________________________________________________ | | | homebrew is the elixir of the gods | | |Article: 573
