UNMARKBDDNODE(3)						   BDD FUNCTIONS						  UNMARKBDDNODE(3)

NAME

       unmarkbddnode - unmarks bdd node with a specified mask.

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.

SYNOPSYS

       #include "bdd101.h"
       long unmarkbddnode( BddSystem, BddNode, Mark )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddunmark    Mark;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node to unmark.

       Mark		   The bit mask.

DESCRIPTION

       unmarkbddnode unmarks the bdd node BddNode with the bit mask Mark, in the bdd system BddSystem.	If a null pointer is  given,  the  default
       bdd system is used.  This function does a AND with the field MARK of the bdd node BddNode, and the complemented bit mask Mark.

RETURN VALUE

       unmarkbddnode returns the number of the differents unmarked nodes.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode;
	  chain_list *Expr;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  printf( "Number nodes: %ld0,
		  markbddnode( (bddsystem *)0, BddNode, 0x0001 ) );
	  unmarkbddnode( (bddsystem *)0, BddNode, 0x0001 );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

NAME

       composebddnode - substitutes a variable by a bdd in another bdd.

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.

SYNOPSYS

       #include "bdd101.h"
       bddnode *composebddnode( BddSystem, BddNode, Variable, BddSubst )
	 bddsystem *BddSystem;
	 bddnode   *BddNode;
	 bddvar     Variable;
	 bddnode   *BddSubst;

PARAMETERS

       BddSystem	   The bdd system.

       BddNode		   The bdd node.

       Variable 	   The variable to find.

       BddSubst 	   The bdd to substitute with.

DESCRIPTION

       composebddnode substitutes all the occurency of the variable Variable in the bdd node BddNode by the bdd node BddSubst, in the  bdd  system
       BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       composebddnode returns the resulting bdd node.

ERRORS

       "variable xxx out of range, error !"
	      The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddcircuit *BddCircuit;
	  bddnode    *BddVariable;
	  bddnode    *BddNode;
	  bddnode    *BddSubst;
	  chain_list *Expr;
	  bddvar	 Variable;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i2" ),
				   createablatom( "i3" ) );
	  BddSubst = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" );
	  Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX );
	  BddNode = composebddnode( (bddsystem *)0, BddNode, Variable, BddSubst );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays (i1 and (i2 or i3)) */
