When I wanted to create XNET, I found that the auto setup button of the model assignment dialog disappeared. Even if you manually assign a model, you can't create XNET in the constraint manager. I use database check and update DRC is also useless.In other file ,then button appeared and enable to creat XNET .
Is there a switch to start XNET? Why is autosetup gone?
What should I do? Thank you
