Yes.  It is an instruction set simulator for the PowerPC.  The 
RTEMS BSP named "psim" runs all RTEMS tests on the simulator.

See the getting started guide and in the tests directory when
you build is "psim" and "psim-gdb" that invoke powerpc-rtems-run
and powerpc-rtems-gdb with the proper arguments.
