SATISFYBDDNODE(3) BDD FUNCTIONS SATISFYBDDNODE(3)

NAME

satisfybddnode - finds a satisfying path for a bdd node.

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 ∗satisfybddnode( BddSystem, BddNode )

bddsystem ∗BddSystem;
bddnode ∗BddNode;

PARAMETERS

The bdd system.
The bdd node.

DESCRIPTION

satisfybddnode finds a simple path throw the bdd BddNode that reaches the constant bdd node one, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

RETURN VALUE

satisfybddnode returns a bdd node that satisfies BddNode.

ERRORS

"index xxx out of range, error !"

The BddNode parameter must be different from the bdd node zero.

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 );
Expr = createablbinexpr( ABL_OR,
createablatom( "i0" ),
createablatom( "i1" ) );
BddNode = addbddcircuitabl( BddCircuit, Expr );
freeablexpr( Expr );
BddNode = satisfybddnode( (bddsystem ∗)0, BddNode );
Expr = convertbddcircuitabl( BddCircuit, BddNode );
/* displays i0 */
viewablexpr( Expr, ABL_VIEW_VHDL );
freeablexpr( Expr );
destroybddsystem( (bddsystem ∗)0 );
destroybddcircuit( (bddcircuit ∗)0 );
