A. Intel® Simics® Simulator Command Reference

5.4.1. Listing Objects in the Target System

In Intel® Simics® simulator environment, the virtual hardware platform is presented in a tree hierarchy of namespace and objects. Each namespace can be expanded down to its sublevel objects as all hardware in an Intel® Simics® target machine is simulated as an object. The first method to inspect hardware is to list objects using the list-objects command as shown below: 
list-objects ["iface"] ["class"] [namespace] ["substr"] [-n] [-a] [-all] [-recursive] [-tree]
Table 10.  Listing Objects in the Target System Using list-objects
Command Description
["iface"] Only lists objects with a particular interface.
["class"] Only lists objects of a particular class.
[namespace] Lists all objects inside the given namespace.
["substr"] Lists all objects containing the given substring – especially useful with –all.
-n Sorts by name instead of by class.
-all Lists objects anywhere in the configuration.
-recursive Lists objects in the current namespace and below.
-tree Prints a tree structure similar to the view in the System Editor.

In the Intel® Simics® simulator CLI, enter the list-objects command. You see that the namespace agilex (which is an object by itself) is defined in the class sm_hps_board. The agilex is the namespace for the target board HPS hardware system. Other name spaces are ethernet_switch0, fpga0, and service_node_cmp0. Names might vary on different systems. 

# Intel Simics simulator CLI

You can inspect the objects under system.board.fpga by entering list-object namespace = system.board.fpga. This returns a list of all objects. The output list can be very long.

To further inspect the details of an object, enter command list-objects namespace = [namespace].[object]. Use the -tree option to view the object connections as a hierarchy. To view the table and tree representation of the HPS hardware system, enter commands as follows. 

# Intel Simics simulator CLI  
# using object “agilex.hps” as an example 

simics> list-objects namespace = system.board.fpga.soc_inst.hps_subsys.agilex_hps

To list out every namespace and object available in an Intel® Simics® simulator environment, use the following commands:
  • list-objects namespace -all : Lists all objects of the main namespace.
  • list-namespaces : Lists all namespaces and sublevel objects.
