Description
The Integrated Logic Analyzer (ILA) debug core allows you to perform in-system monitoring of signals in the implemented design through debug probes on the core. You can configure the ILA core to trigger in real-time on specific hardware events, and capture data on the probes at system speeds.
ILA debug cores can be added to a design by instantiating an ILA core from the IP
catalog into the RTL design, or using the create_debug_core Tcl
command to add the ILA core to the synthesized netlist. Refer to
Vivado Design Suite User Guide:
Programming and Debugging (UG908) for more information on adding ILA debug
cores to the design.
After generating a bitstream from the design, and programming the device with the
program_hw_devices command, the ILA debug cores in the design
are accessible from the Hardware Manager using the get_hw_ilas
command. The debug probes assigned to the ILA debug cores in the design can be
returned with the get_hw_probes command.
Related Objects
ILA debug cores can be added to a design in the RTL source files, or using the
create_debug_core Tcl command. Debug cores can be found in the
synthesized netlist design using the get_debug_cores command. These
are not the hardware ILA debug core objects, hw_ila, found in the Hardware Manager
feature of the Vivado Design Suite, though they are related.
The hardware ILA debug core can be found in the Hardware Manager on the programmed hardware device object, hw_device. You can query the hw_ila of the hw_device as follows:
get_hw_ilas -of [current_hw_device]There are also objects associated with the hardware ILA debug core, such as hardware probes, and the captured data samples from the hw_ila core. You can query the objects associated with the ILA debug cores as follows:
get_hw_ila_datas -of_objects [get_hw_ilas hw_ila_2]Properties
You can use the report_property command to report the actual
properties assigned to a specific HW_ILA. Refer to the
Vivado
Design Suite Tcl Command Reference Guide (UG835) for more information.
The properties assigned to HW_ILA objects include the following:

To report the properties for a specific HW_ILA, you can copy and paste the following command into the Vivado Design Suite Tcl shell or Tcl Console:
report_property -all [lindex [get_hw_ilas] 0]
