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. Frank -- ------------------------------------------------------------------------ Frank 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". ---- Ben Cohen Publisher, Trainer, Consultant (310) 721-4830 http://www.vhdlcohen.com/ vhdlcohen@aol.com Author of following textbooks: * Real Chip Design and Verification Using Verilog and VHDL, 2002 isbn 0-9705394-2-8 * Component Design by Example ", 2001 isbn 0-9705394-0-1 * VHDL Coding Styles and Methodologies, 2nd Edition, 1999 isbn 0-7923-8474-1 * VHDL Answers to Frequently Asked Questions, 2nd Edition, isbn 0-7923-8115 ------------------------------------------------------------------------------Article: 40889

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. BillArticle: 40891
In Xilinx Webpack, is there a place were I can find all the functions/operators supported by the various VHDL libraries? In particular, I need the function which converts an integer to a standard logic vector. I was using a conv_std_logic_vector() function on one implementation on VHDL but it doesn't work on Webpack/ModelSim. I used the following libraries: use IEEE.std_logic_1164.all; use IEEE.std_logic_unsigned.all; use IEEE.std_logic_arith.all;Article: 40892

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...

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!

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.
