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 Universite 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 sys-
tem 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 );
