SYNOPSYS¶
#include "bdd101.h"
bddnode ∗relprodbddnodeassoc( BddSystem, BddNode1, BddNode2, BddAssoc )
bddsystem ∗BddSystem;
bddnode ∗BddNode1;
bddnode ∗BddNode2;
bddassoc ∗BddAssoc;
PARAMETERS¶
- BddSystem
- The bdd system.
- BddNode1
- The first bdd node.
- BddNode2
- The second bdd node.
- BddAssoc
- The variable association.
DESCRIPTION¶
relprodbddnodeassoc computes
BddNode1 AND
BddNode2, and
suppress 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¶
relprodbddnodeassoc returns the computed
bdd node.
ERRORS¶
"bad variable association xxx, error !"
The BddAssoc parameter must a valid variable
association.
