@bmarshall, Your link seems to be dead and couldn't find the files in opencores.org. Could you please send the .zip file to me or upload it to some site and send me the link? Thank you.

Thanks for the link. I was adapting an old NIOS-II 9.0 project to NIOS-II 9.1 and got this error message when generating with SOPC Builder :

opencores >> projects >> i2c
