SYNOPSYS¶
#include "bdd101.h" int delbddassoc( BddSystem, BddAssoc )
bddsystem ∗BddSystem;
bddassoc ∗BddAssoc;
PARAMETERS¶
DESCRIPTION¶
delbddassoc deletes the variable association BddAssoc in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. For all the bdd nodes of the variable association BddAssoc, the number of external reference is decremented.
RETURN VALUE¶
delbddassoc returns 1 if the variable association is found, 0 otherwise.
EXAMPLE¶
#include "bdd101.h"
bddsystem ∗BddSystem;
bddcircuit ∗BddCircuit;
bddnode ∗BddNode;
bddnode ∗BddSubst;
bddnode ∗BddVariable;
bddassoc ∗Assoc;
chain_list ∗Expr;
bddvar Variable;
BddSystem = createbddsystem( 100, 1000, 100, 50000 );
BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
Expr = createablbinexpr( ABL_AND,
createablatom( "i0" ),
createablatom( "i1" ) );
BddNode = addbddcircuitabl( BddCircuit, Expr );
freeablexpr( Expr );
Expr = createablbinexpr( ABL_OR,
createablatom( "i2" ),
createablatom( "i3" ) );
BddSubst = addbddcircuitabl( BddCircuit, Expr );
freeablexpr( Expr );
BddVariable = searchbddcircuitin( (bddcircuit ∗)0, "i0" );
Variable = getbddvarbyindex( (bddsystem ∗)0, BddVariable->INDEX );
Assoc = delbddassoc( (bddsystem ∗)0 );
addbddnodeassoc( (bddsystem ∗)0, Assoc, Variable, BddSubst );
BddNode = substbddnodeassoc( (bddsystem ∗)0, BddSubst, Assoc );
delbddassoc( (bddsystem ∗)0, Assoc );
Expr = convertbddcircuitabl( BddCircuit, BddNode );
/* displays ((i3 or i2) and i1) */
viewablexpr( Expr, ABL_VIEW_VHDL );
freeablexpr( Expr );
destroybddassoc( (bddsystem ∗)0 );
destroybddsystem( (bddsystem ∗)0 );
