Re: [openrisc] Cell not translated

[psandeep@asu.edu]

Hello Richard,
                I am using Xilinx ISE to synthesize or1200. I have written a 
script file to synthesize it. Problem here is that, at the xst prompt, when 
it is analyzing, it reads RAMB4_16.v library and fails. The error msg 
is "Unsupported tri0 net type". Did you get the same msg when you tried 
to synthesize?
This is the first time I am trying to synthesize using Xilinx ISE. If there is 
a more efficient way to do it please let me know. I have been 
comfortable with scripts, so I was trying that out.
Please help!

Regards,
Sandeep.
