I have design for MAX10 include Qsys with Nios running on Quartus 18.1 .
I try to run on Quartus 19.1 and upgrade all IPs. the upgrading successful
but failed when try to Generate RTL . the Error is "xx module not found "
I Have all licenses . the design works on 18.1 .
What module was not found? Can you attach a screenshot of the error(s) and your Platform Designer system? Are there errors in the Platform Designer Messages window before you try to generate the system?
Try to upgrade the IP one by one instead of upgrading all at a time. Refer to link below for details. Then regenerated the hdl again. Below are few links that might be helpful for your reference.
