Method Detail

cellInterfaceDeterminesUniqueNetlistStructure

public 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

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
