Interfacing a Zynq-7000 while retaining the Xilinx JTAG Header

Figure 11 below demonstrates how to connect the JTAG-SMT2 to Xilinx’s Zynq-7000 silicon alongside Xilinx’s 14-pin

JTAG header. In this example the open drain buffers allow both the SMT2 and Xilinx JTAG Header to drive the

PS_SRST_B pin, which may operate a different voltage than the Zynq’s JTAG pins.
