EXISTBDDNODEASSOCOFF(3) BDD FUNCTIONS EXISTBDDNODEASSOCOFF(3) NAME existbddnodeassocoff - computes an existential quantification. SYNOPSIS #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 BddAssoc, 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) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddassoc( (bddsystem *)0 ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 ); SEE ALSO bdd(1) ASIM/LIP6 October 1, 1997 EXISTBDDNODEASSOCOFF(3)
