Logic Cell Insertion - Logic Duplication logic option

A logic option that allows the Fitter to automatically insert buffer logic cells between two nodes without altering the functionality of the design. Buffer logic cells are created from unused logic cells in the device. Logic duplication allows the Fitter to duplicate a logic cell within a LAB when there are unused logic cells available in a LAB.

This option is useful when a design is difficult to fit.

This option is available for supported device(Arriaseries, CycloneIII, CycloneIV, MAXII, MAXV, and Stratixseries) families.

Important: Important: If you want to perform routing back-annotation, turn off the Logic Cell Insertion - Logic Duplication and Auto Register Duplication logic options, run the Fitter, and then back-annotate assignments.
