Opal is a cycle-accurate model of an out-of-order issue processor. The
Simics driver is a one-instruction-per-cycle processor model (i.e.,
in-order).
The Simics model is faster, but does not accurately model a modern
processor. Opal is much slower, more accurate.
Opal only supports the SPARC ISA. Simics (with Ruby) can be either the
SPARC or the x86 ISA.

hello everyone,
I have recently started using gems. At currently
I am successfully able to run ruby and opal and
generate some results for splash bechmarks.
As per my knowledge, we can run ruby with either
opal or native simics. I want to know what are the
major difference/limitations of ruby simulation when
its run using simics instead of opal.
Thanks in advance.
