OpenCores CAN

The problem with any "Open" CAN core is the Bosch license.

I looked into using either the OpenCores CAN core or licensing IP from one of the

other providers however they all work out pretty much the same.

Bosch currently charge aprox 10000 Euros for a license (yep 10 thousand)

This is pretty prohibitive unless you are into really big productions runs.

Other IP implementations include the Bosch license in their release so you

still pay Bosch but indirectly, the cheapest I managed to get down to was

about 7000 Euros which was still too high for us.

In the end we had to resort to using a standard off the shelf CAN peripheral

chip in addition to the FPGA, a real shame but until the license comes down

it was the only way. You could of course just ignore the license but I'm sure

that would be pretty illegal http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif
