[Gems-users] opal sim-start exception and sim-step problem

[Jerry Lin <cosjerry@xxxxxxxxx>]

Hi all:
  I have downloaded Simics 3.0.31 and Gems 2.1 and installed/compiled them.
When I follow the instructions in the QuickStart to load ruby and opal modules,
I encounter a problem when starting opal. Have I done something wrong?
The following is the error message
=================================================
simics> opal0.sim-start "results.opal"
[0]     PC 0xfffffffff0000020   NPC 0xfffffffff0000024  ctx 0x0
Exception error message: Physical memory read raised exception
FP registers: end
: caught exception (#7).
simics> opal0.sim-start "results.opal"

Thanks for helping.
