Thanks. That's more or less how running under Win2K feels though the system
does have 1GB of memory so swapping should not yet be an issue, even for
PAR-the-memory-eater.

No need to qualify, O/S stuff is quite common on the NG  - see the long

That's what I think. Even if the problems were in e.g. MS Office I wouldn't
care since I don't use any of that stuff nor IE nor Outlook The PC is just a
fast compute platform with the only direct interaction coming when I run the
simulator through the GUI. Other than that I use either Cygwin for local
interaction and X-Win (from Starnet) to login to one of the office Unix
boxes.

Dead right. I've taken out the contract ... :-)).

If I can't sort the 2K problems then I will get NTSP6A re-installed, even if
I have to figure out how to do it myself.

My "Webster's Standard American Style Manual" has this to say:

In typewritten material, two spaces follow a period that ends a
sentence.  If the period is followed by a closing bracket, closing
parenthesis, or quotation marks, the two spaces follow the second
mark.  In typeset material, only one space follows this period.

Of course, I can't stop myself *always* typing the two spaces.

Daniel,
You MUST drive TRDY# and DEVSEL# *high* before tri-stating them. These
signals are [so called] sustained tri-state signals. Please refer to
the PCI spec., Appendix B. You should implement 'turn around' state.

Maybe I am not up to date with elementary school methods, but isn't
"creative spelling" simply a stepping stone to "proper" spelling?  I
believe that it parallel to allowing an infant to speak baby talk rather
than correcting them and making them speak the "King's" grammer from the
cradle.  As long as it is straighten out by the time they need to
communicate in writing where is the harm?

That's correct in the context of a typing class (where you are
dealing with mono-spaced fonts). When you're typesetting
(or using a word processor with proportionately spaced fonts)
you should use one space.

When you have a mono-spaced typeface, there are many
bogus spaces sprinkled around in the middle of words
(next to the letter "i" for instance), and it enhances readability
to have two spaces between sentences.

In a proportionate font, there are no gratuitous spaces,
and the extra space is not needed; in fact it is thought
to detract from readability.

Pete, where are you getting all these rules (and "thought"s ;-) from?  I,

Subject: That vs Which // Common confusion among engineer writers
From: vhdlcohen@aol.com (VhdlCohen)
Date: 17 Mar 2002 19:54:45 GMT
Links: << >>  << T >>  << A >>
Since we recently talked about number of "spaces" after a period, I thought I
would bring this up. 
It is a common mistake to misuse the WHICH.  Example from your readme_my_spy:
"it is a good idea to declare a package body which will report an error if the
foreign c library is not being used properly".  Below are the gramatical rules
that will explain it, once and for all.  

THAT verses WHICH: 
The Merriam-Webster 3 dictionary defines:
that pron, pl those : 1: the one indicated, mentioned, or understood <that is
my
house> 2: the one farther away or first mentioned <this is an elm, that's a
maple>
3 : what has been indicated or mentioned <after that, we left> 4 : the one or
ones :
IT, THEY <those who wish to leave may do so>
which pron 1 : which one or ones <which is yours> … 3 — used to introduce a
relative clause and to serve as a substitute therein for the noun modified by
the clause
<the money, which is coming to me,>

Microsoft Word grammar check explains the application rule as: “if the marked
group
of words is essential to the meaning of the sentence, use that to introduce the
group of words. Do not use a comma. If these words are not essential to the
meaning of your sentence, use which and separate the words with a comma”. For
example,
Books, which are generally expensive, can be purchased over the Internet.
Note: The qualifier “which are generally expensive” is not essential to the
meaning of the sentence.

The book that describes VHDL/Verilog guidelines is the Cohen book.
Note: The qualifier “that describes VHDL/Verilog guidelines” is essential
in the
sentence.  Thus, no commas, and the use of "that" (instead of which).
Another example: Operating conditions (e.g., clock speed, operating range,
radiation levels, size, reliability,
reset values, latency, packaging) are design attributes rather than processing
algorithms,
which cannot be expressed in a programming language that does not support
attributes.
The which cannot be expressed... is not asolutely needed, thus a comma prior to
"which".
The "that" in that sentence refers to the programming language, and thus
"which" cannot be used. 

In some sentence structures, the qualifier THAT can be deleted, thus shortening
the
sentence, without affecting the meaning of the sentence. For example,
Spec C is a language that is suitable for specifying systems. // can delete
"that is"
Spec C is a language suitable for specifying systems.

Bottom line: If you want to use "which", PUT a COMMA BEFORE the "which".

Supposedly, yes, but early habits are hard to break, and if you look 
past the hyperbole from the NEA, you will find that the quality of 
teaching has been in steady decline for over 40 years. The problem is 
that it is not straightened out, as the fallacy that pointing out errors 
will damage the psyche persists throughout grade school. In high school, 
there is rarely time for re-addressing fundamentals, other than in 
remedial classes.

One learns by having one's errors corrected, consistently and 
frequently, until correct usage becomes second nature.

In particular, I need the function which converts an integer to

Many years ago, when we first gained access to proportional spacing, and 
when software manuals still taught usage, rather than being only 
reference manuals, I learned that only one space should be used. Some 
page layout programs enforce this rule, preventing the entry of multiple 
spaces from the keyboard.

Frank Vorstenbosch already mentioned:

--My "Webster's Standard American Style Manual" has this to say:

--In typewritten material, two spaces follow a period that ends a
--sentence.  If the period is followed by a closing bracket, closing
--parenthesis, or quotation marks, the two spaces follow the second
--mark.  In typeset material, only one space follows this period.

I just checked with a technical writer friend who agrees, and
says that both the Microsoft Style Manual and AP Style Manual
concur. Unfortunately, I couldn't find either on line, so I can't
quote the text.

First a direct answer to your question: 
in package std_logic_arith you have 
function CONV_UNSIGNED(ARG: INTEGER; SIZE: INTEGER) return UNSIGNED;
Thus
  Std32bits <= std_logic_vector(CONV_UNSIGNED(integer_object, 32)); 

Now for recommendations: 
Don't use the Synopsys std_logic_arith packages, and derivatives because they
are NOT IEEE standards. Instead, use IEEE package NUMERIC_STD.  i also like to
use the derivatives of thes packages, including the package NUMERIC_UNSIGNED. 
There, in the Numeric_Std you can use 
 function TO_UNSIGNED (ARG, SIZE: NATURAL) return UNSIGNED;

  Std32bits <= std_logic_vector(TO_UNSIGNED(natural_object, 32));

Fowler devotes zillions of pages to this, including:

        Each made a list of books that interested him.
            "that" is the defining relative pronoun

        I always buy his books, which have influenced me greatly.
            The clause is non-defining and does not limit "his books"

plus:

        The relations between that, who, and which have come to us from our
        forefathers as an odd jumble...

When looking at the VHDL LRM, it looks like there are two spaces after a
period. 
Whether there are 2 characters spaces in the original text is hard to tell, but
visually, on printed text, it looks like 2 spaces.  The IEEE reviews all specs
before publications.

I didn't, Mr Windoze told me that after I'd remembered the `Xil tools run very
sloooowly on 2K without SP2' problem. I'll check up on this when I'm in the office
again on Tues.

I hope this isn't a variant of the don't-use-NT-SP4 thing of a few years ago.

Why do you think the NEA and the educators want to teach children
poorly?  What possible motivation would they have?  Do you have any
support for your views?  

BTW, I learned by the old methods, and I would not say that I am a
poster child for good spelling in spite of the fact that I have a
Master's degree in engineering and have been writing for the last twenty
years!  I find that spelling (and sometimes grammar) are difficult
subjects and I don't see how learning phonetic spelling would be so
harmful.  In fact, it might be useful if we all tried using it rather
than promoting this absurdly inconsistent scheme that we have now! 

But then maybe this is not the place to debate this topic.  :)

Subject: How to deal with a high fan-out net in FPGA.
From: "Kelvin Hsu" <qijun@okigrp.com.sg>

Hi:

I want to know how am I going to deal with a high fan-out net
in a Spartan-II chip. The basic idea is that I have to delay the reset
signal from another chip for 64 clock cycles in my chip. After that I
use this delayed signal to initialize my registers. I have arround 100
registers in my design.

I tried to instantiate a BUFG for my delayed reset,but ISE won't
synthesize it.

Thanks for your advice.
