  write_order - write the current order of the MDD variables of the flattened
  network
     _________________________________________________________________

   write_order [-h] [-o <type>] [<file>]

   Write the current order of the MDD variables of the flattened network.
   If  no  file  name  is  specified,  the output is written to stdout. A
   sample output is shown here.
  # name                 type            mddId vals levs
  system.choosing0      primary-input       31    2 (61)
  system.p0.pc          latch               32   11 (62, 63, 64, 65)
  

   The  first  column  gives the full hierarchical path name of the node,
   starting  from  the current hierarchical node. The second column gives
   the  type  of  the  node  in  the  flattened  network (see the command
   print_network).  The  third  column gives the MDD id of the node; this
   can be thought of as just another name for the node. The fourth column
   gives  the  number  of  values  that  the multi-valued variable at the
   output of the node can assume. The last column gives the levels of the
   BDD  variables that encode the multi-valued variable (0 is the topmost
   level of the BDD).

   The bits of a multi-valued variable need not appear consecutively (due
   to  dynamic  variable ordering). Each node appears at most once in the
   output  file.  The  nodes in the file appear in ascending order of the
   lowest  level  bit in the encoding of the node's multi-valued variable
   (e.g.  a  node  with  levels  (12,  73) will appear before a node with
   levels (17, 21, 25)).

   To  specify  a variable ordering for static_order, a convenient tactic
   is  to  write out the current ordering, edit the file to rearrange the
   ordering  (or  comment  out  some nodes, using "#"), and then read the
   file  back in using static_order. Note that everything after the first
   column is ignored when the file is read in.

   Command options:

   -h
          Print the command usage.

   -o <type>
          Specify  the network nodes to write out. Type can be one of the
          following:

          all:  Write  out  all  the nodes of the network. This option is
          allowed only if all variables have been ordered.

          input_and_latch: (default) Write out the primary inputs, pseudo
          inputs, latches, and next state variables.

          next_state_node:  Write out the next state variables (node type
          is  "shadow"). This file can be modified and read back in using
          the static_order -s next_state_node command.

   <file>
          File  to  which to write the ordering. By default, the ordering
          is written to stdout.
