NAME

6       applybddnode - applies an operator on two bdd nodes.
7

SYNOPSIS

9       #include "bdd101.h"
10       bddnode ∗applybddnode( BddSystem, Oper, BddNode1, BddNode2 )
11         bddsystem ∗BddSystem;
12         long       Oper;
13         bddnode   ∗BddNode1;
14         bddnode   ∗BddNode2;
15

PARAMETERS

17       BddSystem           The bdd system.
18
19       Oper                The binary operator.
20
21       BddNode1            The first bdd node.
22
23       BddNode2            The second bdd node.
24

DESCRIPTION

26       applybddnode  computes  the  boolean function BddNode1 Oper BddNode2 in
27       the bdd system BddSystem.  If a null pointer is given, the default  bdd
28       system is used.
29

RETURN VALUE

31       applybddnode  returns a pointer to the resulting bdd node with its num‐
32       ber of external reference incremented.
33

ERRORS

35       "bad operator xxx error !"
36              The Oper parameter must be a valid binary operator.
37

EXAMPLE

39       #include "bdd101.h"
40          bddsystem  ∗BddSystem;
41          bddcircuit ∗BddCircuit;
42          bddnode    ∗BddNode;
43          chain_list ∗Expr;
44          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
45          BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
46          addbddcircuitin( (bddcircuit ∗)0, "i0", 0, BDD_IN_MODE_FIRST );
47          addbddcircuitin( (bddcircuit ∗)0, "i1", 0, BDD_IN_MODE_FIRST );
48          BddNode = applybddnode( (bddsystem ∗)0,
49                                  ABL_AND,
50                                  searchbddcircuitin( (bddcircuit ∗)0, "i0" ),
51                                  searchbddcircuitin( (bddcircuit ∗)0, "i1" ) );
52          Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );
53          /* displays (i0 and i1) */
54          viewablexpr( Expr, ABL_VIEW_VHDL );
55          freeablexpr( Expr );
56          destroybddsystem( (bddsystem ∗)0 );
57          destroybddcircuit( (bddcircuit ∗)0 );
