/* 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.

/* 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'.

      leaving the memory in a undefined state. This is the fastest
      option.

        (without quotes).

          A) To send/receive characters from a pair of files, use a file
             channel:

               channel=file:<rxfile>,<txfile>

	  B) To create an interactive terminal window, use an xterm channel:

               channel=xterm:[<xterm_arg>]*

	  C) To create a bidirectional tcp socket which one could, for example,
             access via telnet, use a tcp channel:

               channel=tcp:<port number>

	  D) To cause the UART to read/write from existing numeric file
             descriptors, use an fd channel:

               channel=fd:<rx file descriptor num>,<tx file descriptor num>

          E) To connect the UART to a physical serial port, create a tty
