NAME¶

applybddnode - applies an operator on two bdd nodes.

ORIGIN¶

This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France.

SYNOPSYS¶

#include "bdd101.h"
bddnode ∗applybddnode( BddSystem, Oper, BddNode1, BddNode2 )


  bddsystem ∗BddSystem;


  long       Oper;


  bddnode   ∗BddNode1;


  bddnode   ∗BddNode2;

PARAMETERS¶

BddSystem

The bdd system.

Oper

The binary operator.

BddNode1

The first bdd node.

BddNode2

The second bdd node.

DESCRIPTION¶

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

RETURN VALUE¶

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

ERRORS¶

"bad operator xxx error !"

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 );


   BddNode = applybddnode( (bddsystem ∗)0,


                           ABL_AND,


                           searchbddcircuitin( (bddcircuit ∗)0, "i0" ),


                           searchbddcircuitin( (bddcircuit ∗)0, "i1" ) );


   Expr = convertbddcircuitabl( (bddcircuit ∗)0, BddNode );


   /* displays (i0 and i1) */


   viewablexpr( Expr, ABL_VIEW_VHDL );


   freeablexpr( Expr );


   destroybddsystem( (bddsystem ∗)0 );


   destroybddcircuit( (bddcircuit ∗)0 );
