For RTEMS, we are also using Spike and SIS. You might remember SIS as
the SPARC simulator in gdb. Jiri Gaisler has done a significant work on 
it and
it now supports multi-core Leons and RISC-V and is a standalone simulator
with remote gdb rather than being in gdb.

SIS: https://git.rtems.org/jiri/sis.git/
