The simulator supports several options including the trace option (-t) and the statistics option (-s). Use the option --help for more information.

You can trace the execution of your program using the trace option. The output is a line of trace information for each instruction executed. The trace information gives the execution time so far (in microseconds), and program counter and the disassembled instruction. Source file names and lines numbers are printed where the source was compiled with the debug option. Linker labels are printed too.
