Description
Set or return the current hardware ILA debug core targeted by the Hardware Manager in the Vivado™ Design Suite for programming and debug.
The Integrated Logic Analyzer (ILA) debug core lets you perform in-system debug of implemented designs, or design bitstreams, on a programmed AMD FPGA. The ILA core includes many advanced features of modern logic analyzers, including boolean trigger equations, and edge transition triggers. You can use the ILA core to probe specific signals of the design, to trigger on programmed hardware events, and capture data from the AMD FPGA in real-time. Refer to LogiCORE IP Integrated Logic Analyzer (PG172) for details of the ILA core.
ILA debug cores can be added to a design instantiating an ILA core from the IP catalog into the RTL design, or using the create_debug_core 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.
This command returns the current hardware ILA core as an object, or returns an error if it fails.
Arguments
-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<hw_ila> - (Optional) Specify the hw_ila object to set as the current debug core for programming and debug. The hw_ila must be specified as an object as returned by the get_hw_ilas command. If a ILA debug core is not specified, the current_hw_ila will be returned.
Example
The following example returns the current hardware ILA debug core:
