EXISTBDDNODEASSOCON(3) | BDD FUNCTIONS | EXISTBDDNODEASSOCON(3) |
NAME¶
existbddnodeassocon - 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 ∗existbddnodeassocon( BddSystem, BddNode, BddAssoc )
bddsystem ∗BddSystem;
bddnode ∗BddNode;
bddassoc ∗BddAssoc;
PARAMETERS¶
DESCRIPTION¶
existbddnodeassocon suppress in BddNode, 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¶
existbddnodeassocon returns the computed bdd node.
ERRORS¶
"bad variable association xxx, error !"
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_AND,

BddNode = addbddcircuitabl( BddCircuit, Expr );

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

BddNode = existbddnodeassocon( (bddsystem ∗)0, BddNode, Assoc );
