NAME¶
addbddnodeassoc - adds a bdd node in a variable association.
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" bddassoc ∗addbddnodeassoc( BddSystem, BddAssoc, Variable, BddNode )
bddsystem ∗BddSystem;
bddassoc ∗BddAssoc;
bddvar Variable;
bddnode ∗BddNode;
PARAMETERS¶
DESCRIPTION¶
addbddnodeassoc adds the bdd node BddNode, associated to the variable number Variable, in the variable association BddAssoc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The number of external reference of BddNode is incremented.
RETURN VALUE¶
addbddnodeassoc returns a pointer to the variable association.
ERRORS¶
"variable xxx out of range, error !"

#include "bdd101.h"

bddcircuit ∗BddCircuit;
bddnode ∗BddNode;
