"I am going through the net to download CAN VHDL core. HurriCANe is removed from the ESA site, [..]
[..] or if anyone does have these free versions can you mail me ?"
HurriCANe is not free.
"and the link in opencores site for VHDL CAN core is going to some odd page.
can you please guide me on where i can download this [..]"
I shall attach it in a followup to this post, but you may have difficulty getting it to work. Xilinx ISE could not manage to fit it onto a Virtex2 nor a QPro Virtex Rad Hard xqvr300cb228-4 for me during the few minutes I tried, but it might be possible to get ISE to get it working for a VirtexE if ISE's warnings are surmountable.
