When external trace output is used, either directly or via the Zynq®-7000 Processing System, the output signals must be assigned to appropriate package pins.

The nominal assignment for KC-705 and ZC-706 boards when using the Xilinx® FMC XM105 Debug Card to connect the trace signals to a 38-pin Mictor connector are listed in the following table. The FMC HPC connector pins are also listed, which allows deriving the pin assignment for other boards using the same FMC connector and debug card.

For the KC-705 board, the IOB column indicates pins where it is recommended to add a constraint to place the output flip-flop in the pad to minimize skew. The parameter C_TRACE_OUTPUT should be set to 1 and C_TRACE_DATA_WIDTH should be set to 16 with this pin assignment.

For the ZC-706 board, the MDM trace signals should be connected to the Zynq-7000 Processing System Fabric Trace Monitor (FTM), and the Zynq-7000 Processing System should be configured to output 16 data bits. The parameter C_TRACE_OUTPUT should be set to 2 in this case.
