New System Command (File Menu) (Qsys Pro)
Creates a Qsys Pro system in the current Quartus® Prime working directory. Clicking New System is equivalent to opening Qsys Pro from the Quartus® Prime software.
You must specify a Quartus® Prime project to associate with your Qsys Pro system at the time of new system creation. You can either create a new Quartus® Prime project, or open an existing project.
