Liping,
I think I understand what is causing your problem. You are loading opal
when the processor's PC is pointing to a magic break instruction. Thus,
when Opal is loaded, the first instruction that is executed is the same
magic breakpoint. To get around this, add "c 10" (or "cc 10") after your
first echo statement--this will advance simics a few cycles beyond the
breakpoint, then pause simulation and allow you to load Opal without
re-executing the magic break.
I also note that your script doesn't contain commands to load ruby. You
should be aware that without loading Ruby, Opal assumes a simple,
single-processor memory hierarchy and doesn't simulate coherence or
interconnect.
Regards,
Dan

Hi, All
I use the following script to simulation with opal, but is stops simulation very quickly(From the output, I find that, it stops after 1 instruction).
But it seems work well with Simics only and Simics+Ruby.
Any help? Thanks a lot!
