NAME¶

getbddnodesupport - gives the variable support of a bdd node.

ORIGIN¶

SYNOPSYS¶

#include "bdd101.h"
void ∗getbddnodesupport( BddSystem, BddNode, Mode )


  bddsystem ∗BddSystem;


  bddnode   ∗BddNode;


  int        Mode;

PARAMETERS¶

BddSystem

The bdd system.

BddNode

The bdd node.

Mode

The type of support.

DESCRIPTION¶

getbddnodesupport gives the support of the bdd node BddNode in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. If Mode is BDD_SUPPORT_CHAIN the support is returned using chain_list else it is returned using ptype_list. The support must be freed using the freechain or freeptype functions.

RETURN VALUE¶

getablexprsupport returns a pointer to a chain_list or a ptype_list.

EXAMPLE¶

#include "bdd101.h"


   bddsystem  ∗BddSystem;


   bddcircuit ∗BddCircuit;


   bddnode    ∗BddNode;


   chain_list ∗Expr;


   chain_list ∗Support;


   chain_list ∗ScanSupport;


   bddindex       Index;


   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 );


   Support = getablbddnodesupport( (bddsystem ∗0), BddNode, BDD_SUPPORT_CHAIN );


   for ( ScanSupport  = Support;


         ScanSupport != (chain_list ∗)0;


         ScanSupport  = ScanSupport->NEXT )


   {


     Index = (bddnode ∗)ScanSupport->INDEX;


     printf( "%s ", BddCircuit->NAME_IN[ Index - BDD_INDEX_MIN ] );


   }


   freechain( Support );


   destroybddsystem( (bddsystem ∗)0 );


   destroybddcircuit( (bddcircuit ∗)0 );
