NAME

addbddnode - adds a new bdd node in the bdd system.

See the file man1/alc_origin.1.

SYNOPSIS

#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"

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 );
