xTAG v2.0

Part #: XA-XTAG2
Silicon on Board: XS1-L8A-64-LQ64

The xTAG v2.0 provides a high speed, low latency bridge between USB on the host and fast JTAG connection (up to 10Mbps) on the target. Unlike other adapters, the debug stub is executed on the adapter itself. This ensures lightning quick debug functions, such as single stepping, by massively reducing the communications overhead.

In addition to the standard debug capability, optional UART and xCONNECT ports are supported, providing communication with the xCORE during run time. These ports allow you print to the console and are the key to our very high performance xSCOPE real time instrumentation. These debug functions are completely soft because the xTAG only contains a USB bootloader, allowing debug capability to be changed or improved on the fly via firmware.
