Debug Bridge

Product Description

The Xilinx® LogiCORE™ IP Debug Bridge core is a controller which provides a mechanism to establish a communication channel for debug cores with runtime software. The Debug Bridge usage can be classified into two categories: Tandem with Field Updates and Xilinx Virtual Cable (XVC). These two categories provide the means for communicating with the debug IP (including Memory IP) that is in the design. The Tandem with Field Updates flow allows you to download new functionality into a device over the PCIe® link after the device is initially configured through the Tandem PROM/PCIe. The XVC flow allows you to use debug cores and debug the design over non JTAG interface (for example, Ethernet/PCIe).

Key Features & Benefits

There are two broad classification of Debug Bridge IP functionality, which are supported using four different modes.

  • Tandem with Field Updates and Partial Reconfiguration Solution – User selectable mode From_BSCAN_to_Debug is used to add a Debug Bridge instance in each Reconfigurable Module which would connect to debug cores like ILA, VIO, Memory IP, and JTAG2AXI
  • Xilinx Virtual Cable (XVC) Solution – Three modes are supported:
    • User selectable mode From_AXI_to_BSCAN is used to add a Debug Bridge instance in the design with an Ethernet/PCIe master. This mode is a slave to Ethernet/PCIe master while connecting to debug cores like ILA, VIO, Memory IP, and JTAG2AXI in the same chip
    • User selectable mode From_AXI_to_JTAG is used to add a Debug Bridge instance in the design with an Ethernet/PCIe master. This mode is a slave to Ethernet/PCIe master while bringing out the JTAG pins out of the FPGA through I/O pins. This mode is mainly used to debug design on another board over XVC.
    • User selectable mode From_JTAG_to_BSCAN is used to add a Debug Bridge instance to debug the designs over soft Test Access Port (TAP) controller.
