Abstract
An interactive graphical software tool is provided that can be used to report the configuration data (i.e., the state of the various configuration bits) in a programmed device as well as to probe and stimulate circuits in the programmed device. A graphical or textual representation of the configuration data can be displayed. When used with a programmable device having addressable flip-flops, such as a member of the Xilinx XC6200 family, one embodiment of the invention can change the state of any addressable flip-flop in the configured device. The graphical tool of the invention is preferably implemented using a high level programming language such as Java and features a graphical point and click user interface, remote access to hardware, and symbolic debug capability. According to another aspect of the invention, data can be written into a programmable device using an interactive software tool and a hardware device designed to interface with the programmable device. The software tool can optionally access the hardware device via a network server, thereby enabling remote configuration of the programmable device.
