ADDBDDCIRCUITABL(3)						   BDD FUNCTIONS					       ADDBDDCIRCUITABL(3)

NAME

       addbddcircuitabl - converts an abl expression to a bdd node.

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 *addbddcircuitabl( BddCircuit, Expr )
	 bddcircuit *BddCircuit;
	 chain_list *Expr;

PARAMETERS

       BddCircuit	   The bdd circuit.

       Expr		   The expression to convert.

DESCRIPTION

       addbddcircuitabl converts the abl expression Expr to a bdd node. The BddCircuit is used to translate the atomic expressions  into  variable
       nodes.	If a null pointer is given, the default bdd circuit is used.  If an atomic expression doesn't appear in the BddCircuit input names
       hash table or output names hash table,  then  addbddcircuitabl  adds  a	new  input  by	calling  the  function	addbddcircuitin  with  the
       BDD_IN_MODE_LAST mode.

RETURN VALUE

       addbddcircuitabl returns a pointer to the bdd node translated.

ERRORS

       "bad operator xxx error !"
	      The Expr parameter must be a well defined abl expression.

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 );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays (i0 and i1) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );

COMPOSEBDDNODE(3)						   BDD FUNCTIONS						 COMPOSEBDDNODE(3)

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)) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddsystem( (bddsystem *)0 );
