Method Detail

optimizedLUTInputCone

public static Cell optimizedLUTInputCone(Design design,
                                         EDIFHierPortInst input)

Optimizes the LUT input cone being driven by the provided pin such that chained small LUTs can be replaced by a larger LUT instance. Limited to a single replacement LUT at a time (up to 6 inputs).

Parameters:

design - The current design

input - Input pin driven by a series of LUTs that should be optimized into a single LUT.

Returns:

Returns the resulting cell that was the result of the optimization or null if no changes were made.
