/* 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.

   type = random/unknown/pattern

      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.

   random_seed = 

      random seed for randomizer, used if type = 'random'.

   pattern = 

      pattern to fill memory, used if type = 'pattern'.

   nmemories = 

      number of memory instances connected

   instance specific:

     baseaddr =

     delayw =
