public final class bscan_virtex

extends VisibleAnnotation

implements PreDefinedSchematic

The BSCAN_VIRTEX symbol is used to create internal boundary scan chains in a Virtex or Virtex- E device. The 4-pin JTAG interface (TDI, TDO, TCK, and TMS) are dedicated pins in Virtex and Virtex-E. To use normal JTAG for boundary scan purposes, just hook up the JTAG pins to the port and go. The pins on the BSCAN_VIRTEX symbol do not need to be connected, unless those special functions are needed to drive an internal scan chain. A signal on the TDO1 input is passed to the external TDO output when the USER1 instruction is executed; the SEL1 output goes High to indicate that the USER1 instruction is active.The DRCK1 output provides USER1 access to the data register clock (generated by the TAP controller). The TDO2 and SEL2 pins perform a similar function for the USER2 instruction and the DRCK2 output provides USER2 access to the data register clock (generated by the TAP controller). The RESET, UPDATE, and SHIFT pins represent the decoding of the corresponding state of the boundary scan internal state machine. The TDI pin provides access to the TDI signal of the JTAG port in order to shift data into an internal scan chain.

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)
