public final class muxf5_l

extends CL

implements PreDefinedSchematic

MUXF5_L provides a multiplexer function in one half of a Virtex or Spartan2 CLB for creating a function-of-5 lookup table or a 4-to-1 multiplexer in combination with the associated lookup tables. The local outputs (LO) from the two lookup tables are connected to the I0 and I1 inputs of the MUXF5. The S input is driven from any internal net. When Low, S selects I0. When High, S selects I1. The LO output is used to connect to other inputs within the same CLB slice. (Source: XACT Libraries Guide, Chapter 7 MUXF5_L, Xilinx Corporation, 1999.)

Method Detail

getCellName

public java.lang.String getCellName()

Description copied from class: Cell

Access the cell name associated with a derived class. The cellname field is lazily evaluated on the first call of this method. Can be overriden to make cellname different by instance. If the field does not exist, this defaults to the classname.

Overrides:

getCellName in class Cell

Returns:

the cell name associated with a derived class, null if not declared.

propagate

public final void propagate()

Description copied from interface: byucc.jhdl.base.Propagateable

Used for things that are combinationally propagated like combinational logic and Wires and such.

Specified by:

propagate in interface byucc.jhdl.base.Propagateable

type

public int type()

Description copied from interface: PreDefinedSchematic

This method returns one of the predefined schematic constants to identify the type of this cell.

Specified by:

type in interface PreDefinedSchematic

Returns:

A predefined schematic constant

cellInterfaceDeterminesUniqueNetlistStructure

public final boolean cellInterfaceDeterminesUniqueNetlistStructure()

Description copied from class: Cell

When false, the default behavior of this method, each cell will list itself separately in a netlist, guaranteeing that the netlist will not have invalid data at the expense of a larger file-size. Overriding this method to return true allows JHDL to save memory and netlists to be smaller by sharing the netlist structures that are guaranteed to be identical. NOTE: Do not override this unless every possible condition responsible for structural differences in a class (types and amount of children cells created, and arrangements of wires connected to ports) is included in the cellInterface[] of that class.

Overrides:

cellInterfaceDeterminesUniqueNetlistStructure in class Cell

Returns:

false if not overridden, preventing all memory sharing

main

public static void main(java.lang.String[] argv)

test

public static void test()
