13 years ago --- Quote Start --- top level FSM undefined --- Quote End --- It means that the top level entity name set in your Quartus project can't be found in any of the project files. Besides not adding a file to the project it's mostly brought up by using different names. E.g. you saved a file under a different name and set it as project top. Quartus changes the top entity name then to the new file name, wheter an entity of this name can be found in the file or not.
