I creat a module in qsys and make it as top. but didn't show in Hierarchy, Strangely, some of them are shown.
Could you give me a favor?
Go to Project in Menu Window Tab --> Select add/remove files in project --> select your dete.qip file that just have created. Let me know if it works
Since you have specified the NUC module as top, seem the Quartus did not detect it as top module. Try to remove and add back the project file. Below link is reference for creating Qsys component that might be helpful.
