[Ghdl-discuss] New article how to use GHDL

[Rene Doss]

Hallo,

I have written an article how to simulate with GHDL. This is my effort
to support the GHDL project.
I have the feeling this document is needed for a beginner to get a
better introduction.

On a pratical example (UAR) I show how a testbench and the VHDL
simulation works.
The Uart is simple to configure for different baudrate and has also an
internal FIFO.

I can found it:
http://www.dossmatik.de/ghdl/GHDL_uart_sim.pdf

The UART is very practical example for a hardware developer.



I hope you will enjoy to read this.

Hello Rene,

Thanks for your work. When I am beginning to learn something, I prefer
to have first a practical example where the expected result are shown
(by a screnshot in your document) and which can be copy and paste and
working from A to Z. Then, after I saw that things works as expected, I
am interested to know what I did and start looking on the manuals to
understand every step.

So I believe that your article is helpful as a getting started tutorial.
The only suggestion I have is that it seems helpful to me if the vhdl
files are available for download, as copying and pasting from your pdf
could lead to weird code indentation and possible errors (like copying
by mistake a page number of the document).

Have a nice sunday,
Jonas

Hallo,

I get some responce the attached files in the article can not correct
extracted with all pdf readers.
I have put the VHDL files on my Homepage
http://www.dossmatik.de/ghdl/UART.zip

This is not the perfect solution but at the moment the simplest to
correct this bad function of pdf.


Now enjoy by yourselves at simulation my UART.

Hallo,

last year I wrote an article about ghdl. I was a practical guide how to
simulate an UART example.
After the announcement I got some privat Email, what should I improve or
also some additional requests. Now I can satisfy all desirous. I have
revised and put some new sections in the new version.

addtional topics:
- an example application
- makefile for better workflow
- file read/write in testbench
-VHPI interface


You see many news information for speed up your work.


You can found the article on my homepage:
http://www.dossmatik.de/ghdl/GHDL_uart_sim.pdf

And the example files:

Hallo,

I have got response about my article.
The interface what I use is not VHPI standard. What interface have I
used in my article?
Can anybody answer this question? I would know when I had to change this
in my article.

I think this is not correct. The VHPIDIRECT is standard (ie defined in
the manual) but implementation dependent.
