/* 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  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 
 
     instance specific parameters...
 
   enddevice
 
 
 
   which creates a device instance.

/* MEMORY SECTION
 
 
 
   This section specifies how the memory is generated and the blocks
 
   it consists of.

      Specifies the initial memory values.
 
      'random' generates random memory using seed 'random_seed'.
 
      'pattern' fills memory with 'pattern'.
 
      'unknown' does not specify how memory should be generated,
 
      leaving the memory in a undefined state. This is the fastest
 
      option.
