Hello Steve,

Thanks for your reply.

We have both version of OPB to Wishbone (Verilog and VHDL). At this time
we only have tested the OPB to Wishbone in VHDL. Thus you can connect
all WB slave IP cores.

We are on the way too test the WB to OPB (for master WB) and try it on
the Etehrnet MAC from opencores. 

We work an a project for dynamic bandwith allocation in order to
transmitt video, audio and data on the same media. Basically in will be
Ethernet.

We are on the way to develop a Virtex4FX12 plateform using embeded PPC
as processor with linux OS. But I'm interested to have "low cost"
solution on spartan3E with microblaze and uclinux.

CRESITT INDUSTRIE is an association that work on technolgic transfer
from university to SME/SMI. Our action is regional (Region Centre in
France), 
We orqanize seminars on new technology, training (FPGA, DSP, Linux,
PsoC...) ...
You can visit our website www.cresitt.com for more detail (sorry it is
in frecnh), as well as our data base www.doc-en-ligne.fr (most of
document are in french).
(Sorry John for that discussion a bit out of purpose in your mailing
list).

<----> Hello Christophe,
<----> 
<----> From the code standpoint, our Wishbone<>OPB Bridge is written in
VHDL
<----> and that bridges to the Verilog Mac core; perhaps that's why we
<----> didn't
<----> hit this issue?
<----> 
<----> At any rate, the MAC and MDIO interface is operational and as far
as
<----> XPS
<----> is concerned - it looks just like any standard OPB device that
uses
<----> the
<----> Master+Slave OPB port along with an interrupt.
<----> 
<----> What's your application that you are working on?

<----> Dear Steve,
<----> 
<----> Did you succeed to import directly  the IP as OPB compliant under
<----> Plateform Studio  8.1 SP2? I mean that did you directly take the
IP
<----> form
<----> opencores, connect it with your bridge and import it with the
wizard
<----> directly?
<----> 
<----> We personnaly face problem with verilog project including
parameters
<----> file inculded in a module. The Wizard hangup during the process.
<----> According to Xilinx support this is a bug in version 8.1 that
should
<----> be
<----> fixed on next version.
<----> 
<----> The wizard works properly with VHDL project most of the time. In
the
<----> case of the Ethernet core the mdio INOUT pin can't be connected,
I've
<----> currently a Webcase open on xilinx support on that matter.

<----> <---->
<----> <----> Hello Folks,
<----> <---->
<----> <----> My engineering firm is developing several Microblaze IP
cores
<----> based
<----> <----> on
<----> <----> some of our own IP and some of the opencores IP.
<----> <---->
<----> <----> One of the cores which we have created is an OPB to
Wishbone
<----> <----> interface.
<----> <----> This interface supports master and slave devices allowing
<----> Wishbone
<----> <----> DMA/Mastering within the Microblaze.
<----> <---->
<----> <----> We have created an instance of the OpenCores's 10/100 MAC
and
<----> have
<----> <----> this
<----> <----> now fully operational within the Microblaze.
<----> <---->
<----> <----> We have also created a driver that uses the LwIP stack and
the
<----> Xilinx
<----> <----> MicroKernel. Haven't yet made a linux driver, but this
<----> shouldn't
<----> be
<----> <----> any
<----> <----> trouble using our reference code.
<----> <---->
<----> <----> I am tossing this out here because I have been considering
<----> releasing
<----> <----> two
<----> <----> versions of the core.
<----> <---->
<----> <----> The first version would provide full-speed DMA transfers
of
<----> packets
<----> <----> across this OPB bus. This version would be a "pay" core,
but
<----> will
<----> be
<----> <----> significantly cheaper than any others out there.
<----> <---->
<----> <----> The second version we could release is a complete free
core,
<----> but
<----> we
<----> <----> would "slow-down" the DMA transfers somewhat within our
<----> OPB<>WISHBONE
<----> <----> translator.
<----> <---->
<----> <----> I'm sure you will find this core smaller and faster than
the
<----> Xilinx
<----> <----> EMACs, plus it won't "lock-up" after a time period like
<----> Xilinx's
<----> <----> protection scheme in their Mac.
<----> <---->
<----> <----> I'm happy to release the "Free From FLE" version if some
folks
<----> are
<----> <----> interested in using and are interested in creating a Linux
<----> Driver
<----> <----> which
<----> <----> can be contributed back to the community.
<----> <---->
<----> <----> Are there any takers?
<----> <---->
<----> <----> Thanks for reading
