question about ELC 10.1, and really need help!

[WARNING(db_spice)]No spice simulation to do, please check the cell/process list for any error

this problem maybe happend to many other guys who used to design digital library, but I guess the reasons  are almost diffrent. I'm begging anyone can help me.

Flowing is my work  files
