The Soft Devices Chain

The Soft Devices chain (Figure 1) shows all Nexus-enabled devices, such as 'soft' processors and virtual instruments, found in each FPGA design project targeting a programmable device in the Hard Devices chain. When you use Nexus components in your design at the schematic level, the system automatically connects the TDI and TDO lines of each component's JTAG port, to form a continuous JTAG chain.

Note: The Soft Devices chain only becomes populated with the Nexus-enabled devices for a design, once that design has been programmed into the target device.
