Hi Friends.....
I need to do a project in AHDL.
Please help me to find out some tutorials in AHDL from internet.
Thanks in advance.
Cheers...

Dear friends
To: Miha Dolenc, Isa Servan Uzun
This is not a support forum for PCI builders. Altera and their
distributors got (in my experience) very good support
organizations. If you are willing to contribute to the development
of a free core you are welcome to post it here.
However I can still give you some advice. Buy the 'PCI System
Architecture' from MindShare. Pages 49-54 and 70-73 in the 'pci6432
users guide.pdf' has helped me a lot too.
To: Those making the free core
There are lots of cores in the market. Take a look at the
documentation of one or more of those and you can get a flying
start.
I can only program AHDL myself but if I can help I will be happy. I
got some experience now since I have used the Altera PCI core.
Have Fun

Hi,
I have a 64-bit PCI Board.
There is 32 I/O lines which are directly connected to the FPGA
(Altera
APEX20KE400) on the board.
And there is a 32MB (64-bit * 4M) SDRAM memory on this board.
This board is used to control an external device and acquire data
from it.
I need to read and write data (from files on the computer) from/to
this
SDRAM. And according to the some control signals (coming from I/O
lines)
I need the output a pattern from SDRAM to output I/O lines.
Also I need 3 8-bit Configuration Bytes.
I mean when the user changes this parameter from user interface
software on
the host, the I/O
lines should changes according to this chosen value.
For example,
When the user selects number_of_data (which is one of the 3
configuration
bytes)
is decimal 5 from a pulldown menu, the 8-bit output lines should
change to
"00000101" (binary) state.
This value shall indicate to the external device the number of data
to be
transferred.
My problem is interfacing with the PCI bus. I have Altera pci_mt64
megacore
function. But as I told you before
I have no experience on PCI.
Thanks for your help.

Hi Ponnam! Let me try a question: Why in AHDL?
If I'm right, your Altera compiler works quite fine with VHDL and verilog ...
Regards, Andrés!
