WebNo, a multicycle path is a combinatorial path which has more than one clock cycle delay. The designer makes sure that timing requirements are met (by keeping the inputs stable and sampling the output only after a certain number of clock cycles) and tells the synthesis tool he’s done so by setting a multicycle path constraint.
