Synopsys

#include bdd101.h"
bddnode *existbddnodeassocoff( 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

existbddnodeassocoff suppress in the bdd node BddNode complemented, all the variables associated with something in the variable association BddAs_soc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

Return Value

existbddnodeassocoff 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_NAND,
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 = existbddnodeassocoff( (bddsystem *)0, BddNode, Assoc ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (not i1) */
