Version
25.1.1
Global constraints and project settings affect the entire Quartus® Prime project and all the applicable logic in the design. You often define global constraints in early project development; for example, when running the New Project Wizard. Quartus® Prime software stores global constraints in .qsf files, one for each project revision.
