NAME

       substbddnodeassoc - substitutes a set of variables with a set of bdd node.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗substbddnodeassoc( 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

       substbddnodeassoc  substitutes  in  the  bdd  node BddNode all the variables associated to
       something in the variable association BddAssoc, with the corresponding bdd  node,  in  the
       bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       substbddnodeassoc returns the computed bdd node.

ERRORS

       "variable xxx out of range, error !"
              The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.
       "bad variable association xxx, error !"
              The BddAssoc parameter must a valid variable association.

          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
