SYNOPSYS

 #include "bdd101.h"
 bddnode *applybddnodeterm( BddSystem, Oper, Index, BddNode )
   bddsystem *BddSystem;
   long       Oper;
   bddindex   Index;
   bddnode   *BddNode;
 

PARAMETERS

BddSystem
The bdd system.
Oper
The binary operator.
Index
The index of the terminal bdd node.
BddNode
The bdd node.

DESCRIPTION

applybddnodeterm computes the boolean function BddNode Oper and the terminal node corresponding to Index in the bdd system BddSystem. The Index parameter can take only the two following values BDD_INDEX_ONE and BDD_INDEX_ZERO. If a null pointer is given, the default bdd system is used.

RETURN VALUE

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

ERRORS

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

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 );
    BddNode = applybddnodeterm( (bddsystem *)0,
                                ABL_XOR, BDD_INDEX_ONE,
                                searchbddcircuitin( (bddcircuit *)0, "i0" ) );
    Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
    /* displays (not i0) */
    viewablexpr( Expr, ABL_VIEW_VHDL );
    freeablexpr( Expr );
    destroybddsystem( (bddsystem *)0 );
    destroybddcircuit( (bddcircuit *)0 );
