GETBDDNODESUPPORT(3) BDD FUNCTIONS GETBDDNODESUPPORT(3)

NAME

getbddnodesupport - gives the variable support of a bdd node.

ORIGIN

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

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 );
