1.10.306. ROUTER_LCELL_INSERTION_AND_LOGIC_DUPLICATION

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. This option also allows the Fitter to duplicate a logic cell within a LAB when there are unused logic cells available in a LAB. Using this option can increase compilation time. The default setting of Auto will allow these operations to run when 1) the design requires them to fit the design or 2) the performance of the design can be improved by this optimization with a nominal compilation time increase.
