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 !"
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 );
