NAME¶

isbddvarinsupport - tests if a variable appears in a bdd.

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"
int isbddvarinsupport( BddSystem, BddNode, Variable )


  bddsystem ∗BddSystem;


  bddnode   ∗BddNode;


  bddvar     Variable;

PARAMETERS¶

BddSystem

The bdd system.

BddNode

The bdd node.

Variable

The variable number.

DESCRIPTION¶

isbddvarinsupport tests if the variable number Variable appears in the support of the bdd node BddNode, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE¶

isbddvarinsupport returns 1 if Variable appears, 0 otherwise.

ERRORS¶

"variable xxx out of range, error !"

EXAMPLE¶

#include "bdd101.h"


   bddsystem  ∗BddSystem;


   bddcircuit ∗BddCircuit;


   bddnode    ∗BddNode;


   bddnode    ∗BddVariable;


   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 );


   BddVariable = searchbddcircuitin( (bddcircuit ∗)0, "i0" );


   Variable = getbddvarbyindex( (bddsystem ∗ 0), BddVariable->INDEX ) );


   /* displays 1 */


   printf( "%d", isbddvarinsupport( (bddsystem ∗)0, BddNode, Variable ) );


   destroybddsystem( (bddsystem ∗)0 );


   destroybddcircuit( (bddcircuit ∗)0 );
