ADDBDDNODEASSOC(3) BDD FUNCTIONS ADDBDDNODEASSOC(3) NAME addbddnodeassoc - adds a bdd node in a variable association. SYNOPSIS #include "bdd101.h" bddassoc *addbddnodeassoc( BddSystem, BddAssoc, Variable, BddNode ) bddsystem *BddSystem; bddassoc *BddAssoc; bddvar Variable; bddnode *BddNode; PARAMETERS BddSystem The bdd system. BddAssoc The variable association. Variable The variable number. BddNode The bdd node to add. DESCRIPTION addbddnodeassoc adds the bdd node BddNode, associated to the variable num- ber Variable, in the variable association BddAssoc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The number of external reference of BddNode is incremented. RETURN VALUE addbddnodeassoc returns a pointer to the variable association. ERRORS "variable xxx out of range, error !" The Variable parameter must be less or equal to the BddSystem->NUM- BER_VAR field. 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 = addbddassoc( (bddsystem *)0 ); addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSubst ); BddNode = substbddnodeassoc( (bddsystem *)0, BddSubst, Assoc ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays ((i3 or i2) and 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 ADDBDDNODEASSOC(3)
