Table 1. External Trace Output (C_TRACE_OUTPUT = 1)
Signal Name Interface I/O Initial State Description
TRACE_DATA[C_TRACE_DATA_WIDTH-1:0] TRACE O - Connection to external trace equivalent to the Zynq Trace Packet Output, TPIU, port (see the Zynq-7000 SoC Technical Reference Manual (UG585))
TRACE_CTL O -
TRACE_CLK 1 I -
TRACE_CLK_OUT 2 O -
  1. The nominal frequency of TRACE_CLK is 200 MHz. If another clock frequency is used, the parameter C_TRACE_CLK_FREQ_HZ is set from the connected input clock (by propagation in Vivado IP Integrator) if possible, but must otherwise be manually changed accordingly.
  2. The frequency of TRACE_CLK_OUT is TRACE_CLK divided by 2, nominally 100 MHz with a 90° phase shift, to create a sample point at a stable point of the outputs. The phase shift can be adjusted manually with the parameter C_TRACE_CLK_OUT_PHASE if necessary.
