NAME¶

simpbddnodedcoff - simplifies a bdd with don't cares on its off-set part.

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 ∗simpbddnodedcoff( BddSystem, BddOff, BddDc )


  bddsystem ∗BddSystem;


  bddnode   ∗BddOff;


  bddnode   ∗BddDc;

PARAMETERS¶

BddSystem

The bdd system.

BddOff

The first bdd node.

BddDc

The second bdd node.

DESCRIPTION¶

simpbddnodedcoff simplifies the bdd node BddOff with BddDc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The bdd node BddDc must be included imperatively in the off-set part of the bdd node BddOff.

RETURN VALUE¶

simpbddnodedcoff returns the simplified bdd node.

EXAMPLE¶

#include "bdd101.h"


   bddsystem  ∗BddSystem;


   bddcircuit ∗BddCircuit;


   bddnode    ∗BddOff;


   bddnode    ∗BddDc;


   bddnode    ∗BddNode;


   chain_list ∗Expr;


   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );


   BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );


   Expr = createablbinexpr( ABL_OR,


                            createablatom( "i0" ),


                            createablatom( "i1" ) );


   BddOff = addbddcircuitabl( BddCircuit, Expr );


   freeablexpr( Expr );


   Expr = createablbinexpr( ABL_NOR,


                            createablatom( "i0" ),


                            createablatom( "i1" ) );


   BddDc = addbddcircuitabl( BddCircuit, Expr );


   freeablexpr( Expr );


   BddNode = simpbddnodedcoff( (bddsystem ∗)0, BddOff, BddDc );


   Expr = convertbddcircuitabl( BddCircuit, BddNode );


   /* displays '1' */


   viewablexpr( Expr, ABL_VIEW_VHDL );


   freeablexpr( Expr );


   destroybddsystem( (bddsystem ∗)0 );


   destroybddcircuit( (bddcircuit ∗)0 );
