1.9.3.4. Multicycle Paths

A multicycle path is a path that requires more than one clock cycle to propagate. Specify any multicycle paths in the design in the Multi-Cycle Paths tab of the SCOPE window, or with the define_multicycle_path attribute. You should specify which paths are multicycle to prevent the Intel® Quartus® Prime and the Synplify compilers from working excessively on a non‑critical path. Not specifying these paths can also result in an inaccurate critical path reported during timing analysis.
