/* INTRODUCTION
The ork1sim has various parameters, that are set in configuration files
like this one. The user can switch between configurations at startup by
specifying the required configuration file with the -f <filename.cfg> option.
If no configuration file is specified or1ksim searches for the default
configuration file sim.cfg. First it searches for './sim.cfg'. If this
file is not found, it searches for '~/or1k/sim.cfg'. If this file is
not found too, it reverts to the built-in default configuration.
NOTE: Users should not rely on the built-in configuration, since the
default configuration may differ between version.
Rather create a configuration file that sets all critical values.
This file may contain (standard C) comments only - no // support.
Configure files may be be included, using:
include "file_name_to_include"
Like normal configuration files, the included file is divided into
sections. Each section is described in detail also.
Some section have subsections. One example of such a subsection is:
device <index>
instance specific parameters...
enddevice
which creates a device instance.
