SYNOPSYS

 #include "bdd101.h"
 bddnode *addbddnode( BddSystem, Index, High, Low  )
   bddsystem *BddSystem;
   bddindex   Index;
   bddnode   *High;
   bddnode   *Low;
 

PARAMETERS

BddSystem
The bdd system.
Index
The bdd index.
High
The bdd high pointer.
Low
The bdd low pointer.

DESCRIPTION

addbddnode adds a new node with the index Index, High as HIGH pointer, and Low as LOW pointer in the bdd system BddSystem. If the bdd node exist already addbddnode return its pointer. If a null pointer is given, the default bdd system is used.

RETURN VALUE

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

ERRORS

"index xxx out of range"
The Index parameter must be a valid index.

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 );
    BddNode = addbddcircuitin( (bddcircuit *)0, "i0", 0, BDD_IN_MODE_FIRST );
    BddNode = addbddnode( (bddsystem *)0, BddNode->INDEX, BddNode->LOW, BddNode->HIGH );
    Expr = convertbddcircuitabl( (bddcircuit *)0, BddNode );
    /* displays (not i0) */
    viewablexpr( Expr, ABL_VIEW_VHDL );
    freeablexpr( Expr );
    destroybddsystem( (bddsystem *)0 );
    destroybddcircuit( (bddcircuit *)0 );
