Reveal Analyzer Wizard launched by clicking on Reveal Analyzer button creates a new .rva file only if there is no .rva file in your Lattice Diamond project directory. You cannot create a new Reveal Analyzer file with Reveal Analyzer Wizard with existing .rva file in your project directory.
You can create a new Reveal Analyzer file without having to rename or delete existing .rva file by following the steps below
- Click on File -> Open -> Project to open a project with Reveal core inserted
- Click on File -> New File -> Other File -> Reveal Analyzer to bring up Reveal Analyzer Wizard and go through the necessary steps for creating a new Reveal Analyzer file
