COMPOSEBDDNODE(3) BDD FUNCTIONS COMPOSEBDDNODE(3) NAME composebddnode - substitutes a variable by a bdd in another bdd. SYNOPSIS #include "bdd101.h" bddnode *composebddnode( BddSystem, BddNode, Variable, BddSubst ) bddsystem *BddSystem; bddnode *BddNode; bddvar Variable; bddnode *BddSubst; PARAMETERS BddSystem The bdd system. BddNode The bdd node. Variable The variable to find. BddSubst The bdd to substitute with. DESCRIPTION composebddnode substitutes all the occurency of the variable Variable in the bdd node BddNode by the bdd node BddSubst, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. RETURN VALUE composebddnode returns the resulting bdd node. 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 *BddVariable; bddnode *BddNode; bddnode *BddSubst; 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 ); BddNode = composebddnode( (bddsystem *)0, BddNode, Variable, BddSubst ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (i1 and (i2 or i3)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 ); SEE ALSO bdd(1) ASIM/LIP6 October 1, 1997 COMPOSEBDDNODE(3)
