OpenCores CAN/Ethernet cores

On Thu, 7 May 2009 19:53:36 +0000 (UTC), Jukka Marin <...@pyy.embedtronics.fi

Dear All,

I'm wondering whether to use 10/100 Ethernet and CAN controller chips
(two of each) in a new design or just put cores from OpenCores inside
an FPGA (which we will need in both cases). I'm (still) new to FPGA's
and have never used cores from OpenCores. Has anybody used these cores?
Are they reliable and ready for production use?

The third alternative is to buy commercial IP blocks, but I'm afraid
they might cost more than the old-fashioned way (the production volumes
will be relatively small).

I'd appreciate any facts and/or opinions. :)

If you are in a hurry, use the chips.

Not after looking at the code.

Probably not.

That is correct.

The above is 100% opinion.

You can look at the ehternet cores from MANTARO NETWORKS (http://
http://www.mantaro.com/services/fpga.htm). They have very good costs for
there cores
as they have developed them from there partners in low costs

We are using OpenCores CAN controller for some time now (with a SoC on
Xilinx FPGA). Works great, using it for Low- and HighSpeed CAN
(transceiver next to FPGA) - nothing to complain about :-).
It has the well-known SJA1000 interface, ...

I agree, it works very well.

You need to read the SJA1000 data sheet to find out how to use it.

And you will need to interface the FPGA I/O to some kind of analogue
transceiver chip to drive the bus e.g. TJA1040.

Whose FPGA are you using?

We are going to use Altera Cyclone III (if possible, since we have used
these chips before).
