2.9.4.2. Signal Tap Debugging with a Root Partition

In a project that reuses a root partition, you enable debugging of the root partition and the core partition independently, with separate Signal Tap instances in each partition. In the project that exports the partition, you add the Signal Tap instance to the root partition. Additionally, you extend the debug fabric into the reserved core partition with a debug bridge. This bridge allows subsequent instantiation of Signal Tap when reusing the partition in another project.

You implement the debug bridge with the SLD JTAG Bridge Agent Intel® FPGA IP and SLD JTAG Bridge Host Intel® FPGA IP pair for each reserved core boundary in the design. You instantiate the SLD JTAG Bridge Agent IP in the root partition, and the SLD JTAG Bridge Host IP in the core partition.

For details about the debug bridge, refer to the SLD JTAG Bridge in the System Debugging Tools Overview chapter.
