Hi,

You are not alone!

I am having this exact problem with my qsys component (not using NIOS). I ported my design from 12.1 to 13 and 13sp1. I also regenerated the qsys with the 13.1 components and I also get hundreds of warnings when generating:

No matching role found for rst_controller:reset_out:reset_req (reset_req)The closest I have come to an answer is from:

Where is states that these warnings can be ignored, however I am not convinced that can be ignored and that its not having a detremental effect on my image! I dont know if its a bug with porting a system or what but it seems to only have appeared due to upgrading Quartus.

I hope we can get some help with this issue!

Regards

James
