Right.  This happens because the simulator was not asked to configure
itself for a model of the "Integrator" board.  By default, it provides
a simple process model, with little in the way of simulated hardware
peripherals.  The SID component (model) library includes parts for
several ARM flavour peripherals: they were built to model the old
ARM PID development board.  To the extent that this "Integrator" board
is similar, you may make use of the components by "--board=pid7t" and
related options.  Simulation for different boards involves assembling
models for all the required parts, and configuring sid to use them:
this can be a small or big job.

For a taste, try running
	sid arm-pid-redboot-tksm.conf
(find named file under $prefix/share/sid; it explains its own origins)
then telnet to localhost:5000 (or connect gdb to localhost:5000; can
upload a RAM-startup eCos program).  This configuration brings up
the PID board simulation, preloads an older RedBoot ROM image.
RedBoot shows a command line on uart1, which is connected to TCP
port 5000.  A little tcl/tk gui also appears, so you can
monitor/interact-with the simulation as it's proceeding.
