Synopsys

#include bdd101.h"
bddnode *existbddnodeassocon( BddSystem, BddNode, BddAssoc ) bddsystem *BddSystem;
bddnode *BddNode;
bddassoc *BddAssoc;

Parameters

BddSystem
The bdd system.
BddNode
The bdd node to treat.
BddAssoc
The variable association.

Description

existbddnodeassocon suppress in BddNode, all the variables associated with something in the variable association BddAssoc, in the bdd system BddSys_tem. If a null pointer is given, the default bdd system is used.

Return Value

existbddnodeassocon returns the computed bdd node.

Errors

bad variable association xxx, error !" The BddAssoc parameter must a valid variable association.

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 );
BddVariable = searchbddcircuitin( (bddcircuit *)0, i0 ); Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX ); Assoc = addbddassoc( (bddsystem *)0 ); addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSystem->ONE ); BddNode = existbddnodeassocon( (bddsystem *)0, BddNode, Assoc ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays i1 */
viewablexpr( Expr, ABL_VIEW_VHDL );
freeablexpr( Expr );
destroybddassoc( (bddsystem *)0 );
destroybddsystem( (bddsystem *)0 );
destroybddcircuit( (bddcircuit *)0 );
