Figure 3.6 shows the Multi-ICE connector, CFGEN link and LED.

The CONFIG link is used to enable in-circuit programming of any tile FPGA and PLDs using Multi-ICE (see JTAG scan paths).

The Multi-ICE connector provides a set of JTAG signals that allow JTAG debugging equipment to be used (see JTAG signals). If you are debugging a development system with multiple tiles, connect the JTAG debugging equipment to the Interface Module and the JTAG signals are routed through any connected tiles.
