All Implemented Interfaces:

BooleanFlags, IOPad, PreDefinedSchematic, byucc.jhdl.base.Propagateable, TreeListable

Deprecated. ipads are not necessary. All that is necessary is an obuf, with the input wire assigned to the perscribed pin.

public final class opad_sim

extends CL

implements IOPad, PreDefinedSchematic

OPAD is a single output pad. An OPAD connects a device pin to an output signal of the FPGA. It is internally connected to an input / output block (IOB), which is configured by the XACT software as an OBUF, and OBUFT, an OBUFE, and OFD, or an OFDT.

Method Detail

getCellName

public java.lang.String getCellName()

Deprecated.

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()

Deprecated.

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

cellInterfaceDeterminesUniqueNetlistStructure

public final boolean cellInterfaceDeterminesUniqueNetlistStructure()

Deprecated.

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

type

public int type()

Deprecated.

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

main

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

Deprecated.

test

public static void test()

Deprecated.
