4.4. Getting Device Information from the Intel® Simics® Model

List the devices in an Intel® Simics® model with the devs Intel® Simics® CLI command. Only devices mapped in a memory space are listed with the command. The devs command also displays the memory space and memory map for each device. The following example shows the truncated output from running the devs Intel® Simics® CLI command: 

# Intel Simics simulator CLI

The table shows the path of the devices. The device paths depend on the virtual model. The paths shown correspond to those you see using the Agilex™ 5 E-Series Universal Virtual Platform.

To get device information for a single device, run the devs Intel® Simics® CLI command with the device path information obtained earlier. For example, the devs system.board.fpga.soc_inst.hps_subsys.agilex_hps.pwrmgr.bank.regs command returns a table like the following table: 
#Intel Simics simulator CLI 

simics> devs system.board.fpga.soc_inst.hps_subsys.agilex_hps.pwrmgr.bank.regs
-------------------------------------------------------------------

       subsys.agilex_hps.   subsys.agilex_hps
       pwrmgr.bank.regs     .phys_mem

Examine the registers of a specific device and the current value of them with the print-device-regs Intel® Simics® CLI command. Provide the path of the device register banks (as found with the devs command) as a parameter. For example, the print-device-regs system.board.fpga.soc_inst.hps_subsys.agilex_hps.pwrmgr.bank.regs command returns the following information: 

#Intel Simics simulator CLI 

simics> print-device-regs system.board.fpga.soc_inst.hps_subsys.agilex_hps.pwrmgr.bank.regs

You also can list the object below a specific hierarchy in a virtual platform using the list-objects Intel® Simics® CLI command. In addition to listing the objects, this command indicates the class to which each object belongs.

This information is beneficial when analyzing the components in a virtual platform. The following output is an example of the list-objects command output showing the objects in the board component: 

# Intel Simics simulator CLI 
simics> list-objects namespace = system.board

Remember: The device path information depends on the virtual platform that you use during simulation. The paths here are from the Agilex™ 5 E-Series HPS model in the Agilex™ 5 E-Series Universal Virtual Platform. The paths in the Agilex™ 5 E-Series Intel® Simics® model follow the system.board.fpga hierarchy approach described in Understanding Target Scripts in Intel® Simics® Simulator for Intel® FPGAs User Guide.
