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.

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"  :-) :-)

The CCLK output slew rate is unaffected by the CCLK clock rate, and the

I congratulate you on posting this information.

Xilinx seem to forget theit software is already dongled in a
completely un-hackable way: a Xilinx FPGA/CPLD.

Why dongle on top of that?

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.

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.
