asking for help....

some guidelines for whom who wanna start HDLs learning!

Hi All , 
This message is a reply for a question that we have all asked when we
are starting HDl learning .Please see the reply . I intend to share it
with you after i replied the mail personally ( I think it applies for
many among the peers here ) .. 
================================================================
Hi , 
        Your question is really very important. It is a sort of dilemma when itcomes to what you are addressing at the
starting level to learn HDLs in
general. The thing that could more complicate the process is the
non-availability of Open source EDA tools that could process HDL
languages ( One of our targets in Open source Solutions is to develop
REAL Open EDA tools which needs Software engineers with EE background ).
        There are many free as u stated but Most of them are unreliable. More
over, It distracts the learner as it needs a very tough effort to
understand the tool it self and how to train your self to use it
correctly and make the proper settings for it. Hence, You might find
your self trying to understand the puzzles of the EDA tool rather than
learning the HDL language itself. 
        Don't worry so much, We have all faced the same and We are still
encountering many problems especially when you are involved in an open
source design. It needs a reliable open source tool too. Some times the
designers are forced to use cracked tools to come with a design out.
Now, I'd like to point you to a very good starting point. We need to
digest the basics of the VHDL or verilog. 
        Then what about downloading a free evaluation version from a reliable
EDA vendor like Mentor Graphics or Aldec. You can download an evaluation
version from the software for free for 30 days ( enough time to try and
practice basics ) which could be extended by re-downloading the tool
from another machine and so on ... So i recommend for VHDL that u
download the eval version of ModelSim (mentor-graphics)
        (http://www.model.com/products/release.asp_
You could also download an evaluation version for 20 days from Aldec . a
product called Active-HDL (http://www.aldec.com/ActiveHDL/) 
This is a nice start for tools ... You can always extend your time by
re-downloading the software from another machine and so on ... 
        **When it comes to the 2nd part of the query which is the HDL language
itself You can find tons of on line tutorials about both VHDL and
Verilog. When I start  learning VHDL I went through this one
(http://www.vhdl-online.de/~vhdl/) and you can find on the following
link  a package of some VHDL useful stuff : books, on-line tutorials
..(http://www.cs.ucr.edu/content/esd/labs/tutorial/VHDL_Page.html) .
        Here is also a very useful link with some cool stuff that addresses on
line tutorials for Verilog and VHDL and relevant books to HDls and
digital design (http://www.public.asu.edu/~pvsampa/vlsi.htm) 
I think the on line tutorial from ALdec is good one That i want to try
when i start learning verilog. (we can start together, Company in
learning is very important and usually ends with fruitful results..
There are also some available free e-books right there within the links
provided above. One of the best from charged books are ( K.C.Chang Books
) 
**Digital Design and Modeling with VHDL and Synthesis by K. C. Chang
{Basics of VHDL modeling and coding styles)
**Digital Systems Design with VHDL and Synthesis by K.C. Chang
(AN integrated approach which means Coding, Verification and synthesis )
Also there is ( The designers Guide to VHDL by Peter Ashenden).

Returning back to the free open source tools. I suggest that when you
are a good level that you can start learning to use an open source tool
(which is hard ) like ( ALliance )  http://asim.lip6.fr/alliance.html
it is a complete set of free CAD to compile, simulate and synthesize a
design. It has also a good mailing list that I had just registered to
it. 
        I hope this might be helpful for you. Please let me know if
you have any further queries. 

Best Regards,

        Mohamed A Salem

Re: asking for help....

Dear Friend ,
I hope that the message that I had posted with the title "some
guidelines for whom who wanna start HDLs learning!" might serve as a
partial bridging for the gap you have in resources about HDls.
We would like you to share us the specs of this "IP engine ", SO we can
provide and support you with definite answers for your questions. It
seems that you are still addressing your design from a high level of
abstractions. We need to know more details. I recommend that You post
the specs or direct us to its link and then we can start the
brainstorming with you .. 
Hope the above could be helpful and waiting for more details about your
research .

Awsome project.  I know only a little bit about GIS, but it certainly seems to
be a very interesting area.  Are you looking around for more developers in 
general?  If so, have you considered contacting someone at the USGS to see if 
they would be interesting in helping out with the project?

A handheld GIS app would be very interesting, but right now I don't think I 
have time for another project.  Based on the screenshot it looks like you have
a lot there already.  Is there a site that the code can be downloaded from?

Re: GIS engine under Linux/Unix

Dear Hany, 
I'd like first to thank and congratulate you for this very powerful GIS
engine. I was also waiting for this detailed e-mail from your side that
could shed light for the community about your GIS engine.
I've searched about GIS and this adds some more clarification that I'd
like to share it here with the members.

GIS engine is simply a computer based tool that would be used in mapping
and data manipulation. The tool should address portability between a
wide range of platforms so it could be used in networking applications.
Hany had used the most portable open set of tools that could achieve an
excellent issue of portability. A very simple example of using GIS is
that : Imagine that we are about making a decision  of re-locating in a
new apartment: The decision is about multiple choices we do have in many
different Areas. The decision making will be built from using the GIS
engine ??? HOW ... 

The GIS engine is equipped with a data base for all these geographical
areas and their attributes : 
Other words : It has maps for Heliopolis, Nasrcity, Dokki, Mohandessin,
New Cairo , ......etc ... 
And the attributes could be : Electricity network , water network ,
waster network , clubs , streets , main squares, malls , groceries,
laundries, restaurants, universities, schools, people distributions,
urban compounds , ...... etc .. (THESE are each area attributes ).
Each one of  this attribute is mapped on the AREA geography map as a
LAYER. You can mis layers. for instance, I wanna my sons to be joining a
school. SO i'll recall from the database the ARea map and overlay the
LAYER of schools on it and at the same time i think of transportation
means so I'll recall on it the Bus stations around. Then I could make a
decision if this school is secure enough for the kids to come back early
or it is far away from transportation . All at a glance using the GIS
engine. ( Very simple example and so on .. ) You can choose the
apartment and its AREA upon collection information from the GIS that
could help you in making a decision which is WISE>!

Now , If u need more info and you are interested to know more
technically about this you could be visiting 
http://education.ollusa.edu/edtechnewsv1/whatisGIS.htm
or www.gis.com
I'm really interested to know more.... 

Hany, I'm into hardware as you might know .. So, I'll be so interesting 
in a project like OFOQ when it reaches some advanced stages at its road
map to run the GIS on its platform . Having a PDA that could run a Tiny
part of the GIS engine could be a fancy application. 

I'd to invite you to Host the Project under Handasa Arabia Organization
and start a mailing list after you get some interested developers and
I'm sure that you will have.. and I'm inviting all the members around to
share and participate the development of GeoINFO... 
Finally , Thank you so much for considering HA as a destination for
introducing your powerful GIS engine. 
================
Note : All the information provided in the GIS examples is from a net
search that added to my knowledge about GIS applications. ( correct any
wrong piece if any )

Why that limit ??

What is the license of geoGPG ??
Are we allowed legally to use their symbols ??

The same question as above !

What that  limit ??
May be on older machines that was a reasonable limit, but now gigs of ram are 
normal.

Again, why do we have limits on all of the above ?

Really it is nice application, and we would like to see it progressing.
