public final class tck

extends VisibleAnnotation

implements PreDefinedSchematic

The TCK input pad is connected to the boundary scan test clock, which shifts the serial data and instructions into and out of the boundary scan data registers. The function of the TCK pad is device configuration dependent and can be used as follows. - During configuration TCK is connected to the boundary scan logic. - After configuration, if boundary scan is not used, the TCK pad is unrestricted and can be used by the routing tool as an input/output pad. - After configuration, if boundary scan is used, the TCK pad can be used for user-logic input by connecting it directly to the user logic.

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.

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

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

main

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

test

public static void test()
