8.1.2. Command Return Values

The return value of a command is printed on the console unless it is used as an argument to some other command. Parenthesis () are used to group a command with arguments together, allowing the return value to be used as an argument. The return value can also be used as a namespace in another command. Variables can be used in the same way.

The following capture shows some examples of using the value returned by a command in another command:

#Intel Simics simulator CLI 

simics> $address = 0xffe00000

simics> set $address 20

simics> echo "The value at address " + $address + " is " + (get $address)
The value at address 4292870144 is 20

simics> $id = 0

simics> system.board.fpga.soc_inst.hps_subsys.agilex_hps.core[$id].print-time
Processor             Steps       Cycles        Time (s)
system....core[0] 187271821179  1475824027943  18446.556

simics> $cpu = system.board.fpga.soc_inst.hps_subsys.agilex_hps.core[$id]

simics> $cpu.print-time
Processor             Steps       Cycles         Time (s)
agilex.hps.core[0] 187271821179  1475824027943  18446.556

Parenthesis can also be used to break a command with its arguments across multiple lines, making it easier to read scripts with expressions and nested command invocations.
