NAME

       restoredirvbe - restore connectors directions from behavioral view

ORIGIN

       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

       Web : http://asim.lip6.fr/recherche/alliance/

SYNOPSYS

       #include "mlo.h"
       int restoredirvbe(ptfig)
       lofig_list *ptfig;

PARAMETER

       ptfig		   Pointer to a lofig_list

DESCRIPTION

       The restoredirvbe function read the PORT section of the vhdl behavuoiral view of the figure, restores the externals  connectors	directions
       and order them as indicated in the vbe.

RETURN VALUE

       restoredirvbe returns 1 on success, 0 if there is an error while reading the vbe file, -1 if their is no vbe.

ERROR

       "*** mbk error *** restoredirvbe : no figure given"
	      The ptfig parameter is NULL.
       "*** mbk error *** restoredirvbe : figure %s have more connectors than vbe"
	      Number  of connetors in vbe and in figure must be identical. If the vbe have more connectors, the getlocon function give an error on
	      the unknown connector.
       "*** mbk error *** restoredirvbe : cannot read port well!"
	      To restore the connectors directions, the vbe description must have a port well.
       "*** mbk error *** restoredirvbe : bit_vect neither to nor downto"
	      In a port section of a vbe, the bit vector must have indication of the sens of incrementation.

EXAMPLE

       #include "mut.h"
       #include "mlo.h"
       lofig_list * getgoodlofig(figname, mode)
       char *figname;
       char mode;
       {
       lofig_list *ptfig;
	  ptfig = getlofig(figname, mode);
	  restoredirvbe(ptfig);
	  return ptfig;
       }
