You could have a mail interface for script based synthesis. Customers send in a mail with their HDL and a synthesis script along with a target technology. It runs on the idle computer with the idle license and returns a netlist by mail. This way you would factually be running a design house with specifications written down in hdl and a script, and who could object to that ? I think there would be a great market for this, since there are many small businessis that can not afford a full license for say Synopsys Design Compiler. Best regards, PeterArticle: 17352

A visual C++ development environment is much better than any Unix environment I've ever used. The visual C++ debugger is quite pleasant. Integrated object browsers, documentation, and resource editors make it almost too easy to develop (windows-based) software. I've struggled with Unix debuggers, but never found them easier to use than just putting printf's in my code. > Unix was designed by SW developers who wanted to make a very creative > development environment - IMHO they achieved their goal.

I agree that Unix has an admirable history. Once upon a time it was the best thing around (well except for VMS :) It is especially loved by people who like to develop more Unix tools and gadgets. But for doing other work, Windows is simply more useful. While Unix has thousands of hackers controlling its evolution, Windows has millions of customers and billions of dollars. It has the support of office users, game players, scientific users, hardware developers, multimedia developers, and millions of software developers, too. I agree that evolution applies here, but it looks to me that natural selection favors Windows. I don't like this any more than you do, but I've accepted it. > Mind you, what I see on the net is that SW developers on Windows quite > often use unix tools ported to Windows.

For IEEE and ACM conferences, you should contact IEEE and ACM directly. I know that the FPGA and FCCM proceedings are available that way. For FPL you can contact Springer and Abingdon (the publishers). The pattern for FPL seems to be that the England offerings are published by Abingdon, the non-England ones by Springer (however, several of my proceedings are on loan so I couldn't check). For RAW, I'd try the program committee chair. If it has a professional organization that it is associated with, you can contact them directly.

Hello Everybody, We got a SPARC Workstation from a bankrupt client of us. By coincidence we found out, that this workstation was used as a file and license server for Synopsys tools. We don't know what this is worth, but that company owed us 160.000,--DM (~US$90.000,--) so we would like to sell this workstation. The best offer will get it. The license server has several licenses for the following Ver. 1999 packages: dc_expert ultra plus test compiler bahaviour, verilog, vhdl compiler prime time designware developer ultra FPGA compiler II etc. If someone is interested in this workstation please email me. ruenz@tzk.uni-konstanz.de Best regards FriedhelmArticle: 17357
Things aren't standing still in Linux etc. Currently I, too, still prefer MS VC/Word etc. But looking at code crusader (like MS DevStudio) /word perfect (Word) /gdb gui etc may soon change your opinion. Cygnus are putting together some nice Linux development tools. As a s/w engineer on the side its better to have dev tools that run in more places. Certainly the user support/ bug fixes / additions are considerably better. Anyway at present its keeping Microsoft on their toes, which has got to be good for users everywhere. Who knows in five years they might go the way of IBM. (ie not quite so dominant but still a force) Enough jabbering. This is off-topic.

I'll assume you are building just an up counter, though an up/down counter may be doable, but slower. Build a counter large enough to hold the entire range of values. The counter would essentially be an adder with an output register "count" that feeds back to one input, plus a register "increment" that says how much to add to the value at each step. Also, a seperate exponent logic would be needed, which would be a basic integer upcounter. The counter is initialized to the proper initial bit pattern for the starting mantissa and exponent. We also load the increment counter with the proper value for the stride, assuming that it has exactly the same exponent as the count number (thus, if the counter starts at 10010.0101, and you want to increment by 1 each time, you would set the increment value to 000010000, so that the 1 lines up with the proper bit position of the counter value). Now, if for each upcount you add the increment to the counter, everything works fine until you overflow the mantissa. To deal with this, you have a check that determines when the mantissa will overflow. This is simplest with pure upcounters (vs. up/down counters) with an increment value that has just a single 1 (as opposed to incrementing by 5 or something else), since you can pipeline this detector. For the simple case, you just detect that all bits of the count to the left or even with the 1 in the increment should be a 1. Now, to handle mantissa overflow, you perform the addition just as normal. However, you must shift both the count and the increment values one to the right, and increment the exponent. I'm obivously glossing over some issues, but this should give the basic outline of the system. I'll leave it as an exercise to the reader to get the exact area counts, but I would suspect this would be almost as fast, and about 3x larger or so, than a fixed point, non prescaled counter.

In any event, we're going to use one of the Motorola ColdFire processors for an upcoming project, and after spending a couple of weeks futzing with the GNU compiler, I've decided to buy the Diab Data compiler. Runs on Unix and NT (same price!), looks and smells like the GNU compiler, but it's documented and supported. And they give you some nice BOOKS (dead tree technology) when you pays your money. The GNU compiler documentation looks like it was created by committee. Good luck actually finding anything in it. See, I'm a hardware guy whose programming background is strictly Borland C++, and I want to get my test code up and running ASAFP. The less time spent dealing with cryptic make files, the better. Now, I think that Borland (now Inprise, whatever the fark that means) could make a killing if they ported C++ Builder to Linux. yeah, that's the ticket... On the topic of "Unix apps ported to NT," uh, v5.2 of ModelSim PE uses the same GUI as the Unix version.

For those of you who aren't on the ESNUG mailing list, I just wanted
to say that my annual 'DAC Trip Report' is on the ESNUG archive site
at http://www.DeepChip.com . (This year's trip report is a conglomeration
of 77 DAC-attending engineer's individual trip reports and it covers
everything from C-based design to detailed technical insights on the
latest P&R-related tools. These DAC Trip Reports are very user driven,
so you'll find it cuts through a lot of the marketing crap the EDA
vendors like to push on us.)

They port them to Windows because many engineers are unfortunately
forced to used the OS by their managers and by other software
availability. But, the GNU tools are very elegant and portable.
Not to mention the wide array of tools that are buildable with GNU
toolchains. RTEMS (www.oarcorp.com) is one product buildable with GNU
tools. There are _many_ others.
The most unfortunate thing about Windows tools and the reason I
don't use them is that the visual environments lock you in. They
encapsulate your project so well that it cannot be developed from
remote machines or with other tools. Something I build in Borland
has Borland project files, Borland makefiles, etc. I cannot easily
move it to IBM VisualAge or something else.
On the other hand, GNU runs _everywhere_!!! I can take code on
Solaris and easily port it to HP-UX, Linux, etc. (``easily'' is
used loosely here -- easier than some Borland project).
But then again, that's part of the goal. Borland doesn't want
you to use IBM VisualAge, so they hide everything so deep that you
never get a usable Makefile. For "helloworld.c" you get some
obfuscated 3000 line Makefile that would never run anywhere else.
Not to mention 2 megabytes of project organization.
Cheers,
Jake

Hello, I have a requirement to expand a 8051 type microprocessor bus to a minimum of 50 latched I/O pins and up to 144 in some configurations. When I posted this on comp.arch.embedded one suggestion was to use the 9572XL from Xilinx. This chip does seem to be a very good low cost possibility. My main requirements are low cost. The CPLD/FPGA will interface to an 8 bit bus with a 80 nanosecond cycle time, but if necessary the bus can be stretched to 1,000 nanoseconds (EZ-USB). I prefer 3.3V if it is TTL compatible, but 5V could be used also. The other requirement is low power. I have about 20 mA for the CPLD/FPGA (at low clock frequency). Is the 9572XL a good choice? It comes in a 100 pin package for about $3 in low quantity. Thanks for any help. JamesArticle: 17373
