The AMD LogiCORE™ IP Debug Bridge core is a controller which connects the JTAG interface to debug cores in the design.
The 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 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).
There are two broad classification of Debug Bridge IP functionality, which are supported using four different modes.
Virtual Cable (XVC) Solution – Three modes are supported:
Certain AMD technologies may require third-party enablement or activation. Supported features may vary by operating system. Please confirm with system manufacturer for specific features. No technology or product can be completely secure.
