Using user-defined debug probes (also called hw_probes) in the Hardware Manager allows you the ability to create probes from combinations of physical ILA probe ports and constant values. You can then use these probes in the Trigger Setup or Waveform windows in the Hardware Manager. On successful creation of these probes, they are listed in the Debug Probes window as part of the debug core they were associated with during creation.

You can create the following types of user defined probes:

  • An ILA probe port.
  • One or more constant values of 0 and/or 1.
  • A mix of ILA probe port and constant values.
    Important: User-defined probes that involve constant values can only be used in the Waveform window. They cannot be used in the Trigger Setup window.
    Tip: You can only create user-defined probes on ILA debug cores. Creating user-defined debug probes for VIO cores is not currently supported.
