ISBDDVARINSUPPORT(3) BDD FUNCTIONS ISBDDVARINSUPPORT(3)
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 Universite 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 !"
The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.
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 );
