NAME¶
existbddnodeassocoff - computes an existantial quantification.
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"
bddnode ∗existbddnodeassocoff( BddSystem, BddNode, BddAssoc )
bddsystem ∗BddSystem;
bddnode ∗BddNode;
bddassoc ∗BddAssoc;
PARAMETERS¶
- BddSystem
- The bdd system.
- BddNode
- The bdd node to treat.
- BddAssoc
- The variable association.
DESCRIPTION¶
existbddnodeassocoff suppress in the
bdd node
BddNode
complemented, all the variables associated with something in the variable
association
BddAssoc, in the
bdd system
BddSystem. If a
null pointer is given, the default
bdd system is used.
RETURN VALUE¶
existbddnodeassocoff returns the computed
bdd node.
ERRORS¶
"bad variable association xxx, error !"
The BddAssoc parameter must a valid
variable association.
EXAMPLE¶
#include "bdd101.h"
bddsystem ∗BddSystem;
bddcircuit ∗BddCircuit;
bddnode ∗BddNode;
bddnode ∗BddSubst;
bddnode ∗BddVariable;
bddassoc ∗Assoc;
chain_list ∗Expr;
bddvar Variable;
BddSystem = createbddsystem( 100, 1000, 100, 50000 );
BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
Expr = createablbinexpr( ABL_NAND,
createablatom( "i0" ),
createablatom( "i1" ) );
BddNode = addbddcircuitabl( BddCircuit, Expr );
freeablexpr( Expr );
BddVariable = searchbddcircuitin( (bddcircuit ∗)0, "i0" );
Variable = getbddvarbyindex( (bddsystem ∗)0, BddVariable->INDEX );
Assoc = addbddassoc( (bddsystem ∗)0 );
addbddnodeassoc( (bddsystem ∗)0, Assoc, Variable, BddSystem->ONE );
BddNode = existbddnodeassocoff( (bddsystem ∗)0, BddNode, Assoc );
Expr = convertbddcircuitabl( BddCircuit, BddNode );
/* displays (not i1) */

destroybddassoc( (bddsystem ∗)0 );
destroybddsystem( (bddsystem ∗)0 );
destroybddcircuit( (bddcircuit ∗)0 );
