Note the following limitations of the waveform viewer.

  • Signals internal to the AI Engine can be viewed using VCD. They are not integrated in the general XSIM Waveform GUI.

  • CIPS, (QEMU model) which executes the software program, is purely a functional model with no timing accuracy. The NoC, DDR memory, and AI Engine are cycle-approximate models.

  • Bandwidth and latency estimation are approximate, based on the accuracy of the individual IP models.
