I believe that the "dongle" is no longer required for M1 software. If you know how to edit your Volume Serial number, please let us all know how! It's easy to change the volume label (via the LABEL dos shell command), but I haven't discovered an easy wayto change the "Volume Serial Number".

Actually I forgotten about the MS-DOS debug command, which surprisingly, is
still provided with windows-95. This is the easiest way to change the
serial number without linux, but be very careful (back up your files!), as
debug is not very forgiving:
C:\>debug
l 0 2 0 1 - load one sector beginning with sector 0 of
drive 2 (C:) into address 0 (of some segment)
e 27 - hex entry mode
DD <SPACE> CC <SPACE> BB <SPACE> AA <RETURN>
d 0 - display to verify results
w 0 2 0 1 - write boot sector back to hard drive
q - quit

David, I have checked into this and the numbers are accurate. What might be confusing you is that the data sheet shows a pin to pin setup between the input and the clock pin. The software accurately models the input delay and the clock delay getting to that FF instead of lumping it all into a setup time on the FF. If you have any other questions about where we are putting the delays, let me know. SteveArticle: 7653
The key is for the Metamor VHDL compiler only. This requirement is due
to a licensing agreement with Metamor and will go away when Xilinx
moves to FPGA Express as their VHDL synthesis tool. You can tie the
FlexLM license to your ethernet address instead of your hard drive's
volume ID. Customer service should be able to return your license
agreement in less than a day if you supply them with your serial
number.

Hi,
Well developped and explained algorithms are programming language
independent. VHDL is just another programming language in this
respect.
I like particularly following book on algorithms :
author = {Cormen, Thomas H. and Charles E. Leiserson and
Ronald L. Rivest},
title = {Introduction to Algorithms},
publisher = {MIT Press/McGraw-Hill},
year = 1990
I did implement already f.i. red-black trees (for sparse ram models)
and bitonic sort out of this book in VHDL. Worked out well.
Kind regards,

Hi.
We're about to build a successor of our embedded transputer based
controller
( see http://www-mp.informatik.uni-mannheim.de/~kugel/lcmdoc.html ).
The new version should have the following features:
32 bit CPU @ 50MIPS, probably Hitachi SH-3 / 7708 or Hyperstone
E1-32
IEEE 1394 (firewire) host port @ 400MBit/S (or 200MBit/s)
Xilinx XC4013 FPGA as coprocessor and target system interface device
approx. 2MB high speed ram plus 16MB optional DRAM
I am interested in experience or comments on RTOS and development tools
(C, C++, Debugger) for
the two micros and firewire implementations, especially 400MBit/s with
FPGA or CPLD
implementation of LLC.
Thanks,
Andreas

I normally try to avoid plugging my book directly on this newsgroup, but
since you asked about such specific topics, I thought it appropriate
this time.
Chapter 17 of The Designer's Guide to VHDL deals specifically with using
access types (pointers) to implement abstract data types in VHDL.
Section 17.3 includes as examples a circular buffer FIFO, and an ordered
collection container ADT implemented using a doubly-linked list.
Using the material in this chapter as a basis, you should be able to
generalize to other linked data structures described in textbooks on
data structures and algorithms. You might find books based on Ada the
most useful, since VHDL's type system is very closely related to that
of Ada. One pointer to start with is
J. M. Feldman, Data Structures with Ada, Prentice Hall, Englewood
Cliffs, NJ, 1985.
Look for others in your local academic library catalog.
BTW, you can find info about my book in my web page (URL below).
Cheers,
PA

I have no intention of illegally copying their software (except to install
it on my laptop, which I done with their old software). Who would I copy it
for? I want customer support, the software is for me personally and I just
payed a lot of money for it. I was being sarcastic because the
partition serial number offers no security, whereas the hardware key is
nearly impossible to break and I originally thought that they were going to
require both. I mean, why would they want the partition serial number when
they already had a perfectly secure hardware key?
I was annoyed because their web-based license generator gives you only one
chance to generate the license.dat file (based on your hardware key,
customer ID and partition serial number). I entered the wrong number and
couldn't run the software (I was thinking that they must allow you to change
the serial number since people upgrade their hard drive all the time, so I
entered the example serial number that they gave, thinking that I could
just go back and change it to the real one later).
In the time it took for tech. support and then customer service to return my
call (they did eventually call me back after a day), I had fixed the
problem. My partition's serial number is now the example one given on the
web site :-)
Incidentally, I'm told that the ethernet address offers no security either.
Supposedly for $100 you can buy an ethernet card with a programmable
hardware address. You can't put several of those on a network of course,
but you can have several ethernet cards in each machine (but maybe not in
windows, I don't know). But according to the release notes "Xilinx strongly
recommends that you use the Ethernet address instead of the C: drive serial
number" :-) :-)

A Xilinx support engineer told me once it is done to limit their tech support workload. But Xilinx have often said that software profits are only a very small part of their overall profits. In that situation, it is sound business to give the stuff away FOR FREE. I know the other argument for charging steep prices: Viewlogic (etc) charge a lot of licensing *their* s/w to Xilinx. But how many millions does it take to write one's own schematic entry / simulation program, which *could* then be given away? Presumably Xilinx bought Neocad mainly because Neocad could have produced silicon-vendor-independent libraries, and thus made designs portable between silicon vendors. Xilinx's worst nightmare.

In which case it would be a good idea to *first* make a copy of the little EEPROM on the ethernet card :) In case the LAN card packs up after the vendor stops supporting this licensing method, in a year or two's time.

A few thousand dollars is trivial for a business which is convinced that this tool is fundamental to doing business effectively. It's not so trivial to an engineer trying to sell his boss on the idea that it might be worthwhile. Such prices are typically unaffordable to anyone who can't *prove* that such a tool is *essential*. This shuts out a lot of outfits which might become customers but need to experiment and get people sold on it first. As for expecting quality software for free, do you expect quality IC databooks for free? It costs a lot of money to produce those things, you know. (Have you priced specialty technical books lately?) Yet somehow, people who are in business to sell *ICs* have figured out that it's worth giving the databooks away rather than trying to charge $100 each, because they sell more *ICs* that way. Even the ones who do charge for databooks are not recovering much more than shipping and handling costs. Ask any of them, and they'll tell you that treating their databooks as a profit center, rather than as a marketing tool, would be shooting themselves in the foot... if not the head. Most companies that want to sell ICs spend a lot of money and go to a lot of effort to make it as easy as possible for engineers to make use of their products. Unfortunately, the FPGA companies haven't yet figured out that their product is FPGAs, not software. In this business, shooting yourself in the foot is considered standard practice. >> >The feed-the-bits-in algorithm for *some* FPGAs is published. Not all. >> You mean some aren't?

This just in from our paper designs department: the XC4062XL and XC4085XL are sooo big... The J32 (www3.sympatico.ca/jsgray/homebrew.htm) (a 32-bit RISC in half a XC4010) processor's datapath, if redesigned for XC4000XL, should fit nicely in 16 rows by 8-9 columns of CLBs. This got me thinking: 16x9 datapath 16x5 (guess) control logic 16x6 16-entry by 4-word-line instruction cache 16x2 page mode DRAM controller (also reqs. 40-50 IOBs) ---------------------------------- 16x22 integrated 32-bit RISC processor (32-bit instructions) 8x22 integrated 16-bit RISC processor (16-bit instructions) Assuming careful floorplanning, it should be possible to place six 32-bit processor tiles, or twelve 16-bit processor tiles, in a single 56x56 XC4085XL with space left over for interprocessor interconnect. Also the number of processor tiles can be doubled if we eschew the I-cache and simplify the microarchitecture -- though performance would greatly suffer. Jan Gray Redmond, WAArticle: 7674
