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 );
