Description

Reset the trigger and capture configuration properties on the specified ILA debug core, and the TRIGGER_COMPARE_VALUE and CAPTURE_COMPARE_VALUE properties on the core's debug probes.

Properties of the hw_ila object are configured with the set_property command in preparation for the run_hw_ila command to configure the ILA core on the hw_device. This command restores the user-configurable properties on the specified hw_ila to their default settings. Refer to the Vivado Design Suite User Guide: Programming and Debugging (UG908) for more information on these properties.

The default properties are:
  • CONTROL.DATA_DEPTH is set to the MAX_DATA_DEPTH of the hw_ila object.
  • CONTROL.TRIGGER_POSITION 0
  • CONTROL.WINDOW_COUNT 1
  • CONTROL.TRIGGER_MODE BASIC_ONLY
  • CONTROL.TRIGGER_CONDITION AND
  • CONTROL.TRIG_OUT_MODE DISABLED
  • CONTROL.CAPTURE_MODE ALWAYS
  • CONTROL.CAPTURE_CONDITION AND
  • TRIGGER_COMPARE_VALUE eq1'bX (on the hw_probes)
  • CAPTURE_COMPARE_VALUE eq1'bX (on the hw_probes)

This command operates silently, returning nothing if successful, or returning an error if it fails.

Arguments

-reset_compare_values [ true | false ] - (Optional) Reset the TRIGGER_COMPARE_VALUE and CAPTURE_COMPARE_VALUE properties on the hw_probes associated with the specified hw_ila object. This is a boolean argument that is TRUE, or enabled, by default. If -reset_compare_values false is used, the compare value properties on the probes are not reset. In this case, the properties on the hw_ila are reset, but the properties on the hw_probes are left as currently configured.

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<hw_ilas> - (Optional) Specify one or more hw_ila objects to reset. The hw_ila objects can either be specified as objects returned by the get_hw_ilas or current_hw_ila commands, or specified by name. If the hw_ila is not specified, the current_hw_ila will be reset.

Example

The following example resets all hw_ila debug cores on the current device: 
reset_hw_ila [get_hw_ilas]
