The limitations of the trace view data visualization feature are as follows.

  • 64-bit non-vector window data types are displayed as two 32-bit high and low values.

    For example, an unsigned, 64-bit integer 0x0000000100000002 is displayed as 2L and 1H separately. L and H represent low and high 32 bits.

    Another example is a complex 32-bit value where the real 32 bits are displayed first, followed by the imaginary 32 bits.

  • The input_pktstream/output_pktstream data type is displayed in integer format.
  • Kernel names and instance names can be displayed using the Vitis analyzer for templated class. However, templated class name is not supported.
  • Kernel functions are not visible in the trace if they are inlined by the AI Engine compiler.
  • Helper functions called inside the kernel function are not visible in the trace.
