SIMPBDDNODEDCOFF(3) BDD FUNCTIONS SIMPBDDNODEDCOFF(3)

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 );
