NAME

       applybddnodeite - computes the IF-THEN-ELSE logical operation.

SYNOPSYS

       #include "bdd101.h"
       bddnode ∗applybddnodeite( BddSystem, BddIf, BddThen, BddElse )
         bddnode   ∗BddSystem;
         bddnode   ∗BddIf;
         bddnode   ∗BddThen;
         bddnode   ∗BddElse;

PARAMETERS

       BddSystem           The bdd system.

       BddIf               The IF bdd node.

       BddThen             The THEN bdd node.

       BddElse             The ELSE bdd node.

DESCRIPTION

       applybddnodeite  computes the following logical function (BddIf AND BddThen) OR ((NOT BddIf) AND BddElse)
       in the bdd system BddSystem.  If a null pointer is given, the default bdd system is used.

RETURN VALUE

       applybddnodeite returns a pointer to the resulting  bdd  node  with  its  number  of  external  reference
       incremented.

EXAMPLE

       #include "bdd101.h"
          bddsystem  ∗BddSystem;
          bddcircuit ∗BddCircuit;
          bddnode    ∗BddNode;
          chain_list ∗Expr;
          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
          addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );
          addbddcircuitin( (bddcircuit ∗)0, "i1", 0, BDD_IN_MODE_FIRST );
          addbddcircuitin( (bddcircuit ∗)0, "i2", 0, BDD_IN_MODE_FIRST );
          BddNode = applybddnodeite( (bddsystem ∗)0,
                                     searchbddcircuitin( (bddcircuit ∗)0, "i0" ),
                                     searchbddcircuitin( (bddcircuit ∗)0, "i1" ),
                                     searchbddcircuitin( (bddcircuit ∗)0, "i2" ) );
          Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
          /* displays ((i0 and i1) or ((not i0) and i2) */
          viewablexpr( Expr, ABL_VIEW_VHDL );
          freeablexpr( Expr );
          destroybddsystem( (bddsystem ∗)0 );
          destroybddcircuit( (bddcircuit ∗)0 );
