COFACTORBDDNODE(3) BDD FUNCTIONS COFACTORBDDNODE(3) NAME cofactorbddnode - computes the generalized cofactor. SYNOPSIS #include "bdd101.h" bddnode *cofactorbddnode( BddSystem, BddNode1, BddNode2 ) bddsystem *BddSystem; bddnode *BddNode1; bddnode *BddNode2; PARAMETERS BddSystem The bdd system. BddNode1 The first bdd node. BddNode2 The second bdd node. DESCRIPTION cofactorbddnode computes the generalized cofactor of BddNode1 by BddNode2, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. RETURN VALUE cofactorbddnode returns the resulting bdd node. ERRORS "index xxx out of range" The BddNode2 parameter must be different to the zero bdd node. EXAMPLE #include "bdd101.h" bddsystem *BddSystem; bddcircuit *BddCircuit; bddnode *BddNode1; bddnode *BddNode2; bddnode *BddNode; chain_list *Expr; BddSystem = createbddsystem( 100, 1000, 100, 50000 ); BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem ); Expr = createablbinexpr( ABL_OR, createablatom( "i0" ), createablatom( "i1" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); Expr = createablbinexpr( ABL_AND, createablatom( "i0" ), createablatom( "i1" ) ); BddNode2 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); BddNode = cofactorbddnode( (bddsystem *)0, BddNode1, BddNode2 ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays '1' */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 ); SEE ALSO bdd(1) ASIM/LIP6 October 1, 1997 COFACTORBDDNODE(3)
