As czeh's post, i can use tcl-tk communicate with virtual jtag and use it to debug my fpga design. Also i can use VJ to test my fpga design,eg.. i can send data to fpga, and can read data from fpga for offline analyzing. As attahced shows, i have designed one debug station used for my current designs debugging and testing.
