/* INTRODUCTION

   The or1ksim have various parameters, which can be set in configuration

   files.  Multiple configurations may be used and switched between at

   or1ksim startup.

   By default, or1ksim loads condfiguration file from './sim.cfg' and if not

   found it checks '~/.or1k/sim.cfg'. If even this file is not found or

   all parameters are not defined, default configuration is used.

   Users should not rely on default configuration, but rather redefine all

   critical settings, since default configuration may differ in newer

   versions of the or1ksim.

   If multiple configurations are used, user can switch between them by

   supplying -f  option when starting simulator.

   This file may contain (standard C) only comments - no // support.

   Like normal configuration file, this file is divided in sections,

   where each section is described in detail also.

   Some section also have subsections. One example of such subsection is

   block:

   device 

     instance specific parameters...

   enddevice

   which creates a device instance.

/* MEMORY SECTION

   This section specifies how is initial memory generated and which blocks

   it consist of.

   memory_table_file = ""

      loads memory table from filename. If filename does not exists in the

      current directory, it is loaded from ~/.or1k/.

      Memory table file structure is as follows:

        start_address1 length1 type1 [ce1 [delayr1 [delayw1]]]

        start_address2 length2 type2 [ce2 [delayr2 [delayw2]]]

        start_address3 length3 type3 [ce3 [delayr3 [delayw3]]]

      Example:

        00000100 00001F00 flash 3 100

        80000000 00010000 RAM

   type = random/unknown/pattern

      specifies the initial memory values. 'random' parameter generate

      random memory using seed 'random_seed' parameter. 'pattern' parameter

      fills memory with 'pattern' parameter and 'unknown' does not specify

      how memory should be generated - the fastest option.

   random_seed = 

      random seed for randomizer, used if type = random

   pattern = 

      pattern to fill memory, used if type = pattern
