Class Wire

Object

com.xilinx.rapidwright.device.Wire

All Implemented Interfaces:

WireInterface

public class Wire
extends Object
implements WireInterface

This class represents the device object called a wire in Vivado. It is uniquely identified in a device by the tile it belongs to and the specific wire within the tile, referred to by both a name and index that is unique to the tile type. Wire objects are dynamically created as when the device object is loaded, no wire objects are instantiated. Created on: Oct 8, 2015
