ContributionsMost RecentMost LikesSolutionsIssue After Upgrading Nios II from Version 16.0 to 18.0 I recently upgraded Nios II from version 16.0 to 18.0 and encountered an issue with my project. After the upgrade, I received the following alarm message: "The project description file (.project) for 'xxxx(My project name)' is missing. This file contains important information about the project. The project will not function properly until this file is restored." Could you please provide guidance on how to resolve this issue? Furthermore, I would also like to inquire about the installer for Quartus 16.0. If you could provide information on where to download it or confirm its availability, I would greatly appreciate it.
