  read_blif_mv - read a blif-mv file
     _________________________________________________________________

   read_blif_mv [-c] [-h] [-r] [-v] <file_name>

   Reads  a blif-mv file into VIS. The existing hierarchy for the blif-mv
   file  previously  read in is overwritten upon a successful read. If an
   error  is  detected  while  reading  a file, the previous hierarchy is
   preserved.

   Command options:

   -c
          Semi-canonicalize   all   the   tables   in   each  model.  The
          canonicalization  process,  assigns a linear order to the table
          rows  and  columns,  based on the value of their entries. For a
          table  with  binary  valued  entries, this value is exactly the
          number  of  1's in the row or column. Once this linear order is
          assigned,  the  rows and columns of the table are swapped so as
          to order rows and columns with higher value at the beginning of
          the   corresponding   row   or   column  order.  It  is  called
          semi-canonicalization  because two tables representing the same
          logic function need not have the same canonical form.

   -h
          Print the command usage.

   -r
          If  set,  the  program  replaces the subhierarchy rooted at the
          current  node with a new hierarchy specified by a blif-mv file.
          The  file  to  be  read  in  has  to be compatible with the i/o
          interface  of  the  current  hnode (the same i/o names with the
          same domains). Otherwise, the current hierarchy is kept intact.
          If  -r  is not specified, the entire hierarchy is replaced, not
          just the subhierarchy at the current node.

   -v
          If  set, the program prints out all the unused variables in the
          blif-mv  file.  Otherwise,  only a warning is printed that some
          variables are not used.

   <file_name>
          blif-mv file to be read in.
