IMPLYBDDNODE(3) BDD FUNCTIONS IMPLYBDDNODE(3) NAME implybddnode - computes a bdd that implies a conjonction of two bdd nodes. SYNOPSIS #include "bdd101.h" bddnode *implybddnode( 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 implybddnode tests if the intersection of BddNode1 and not BddNode2, ex- ists, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. RETURN VALUE implybddnode returns the bdd node zero if there is no intersection, and a computed bdd node otherwise. EXAMPLE #include "bdd101.h" bddsystem *BddSystem; bddcircuit *BddCircuit; bddnode *BddNode1; bddnode *BddNode2; bddnode *BddImply; 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" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); BddImply = implybddnode( (bddsystem *)0, BddNode1, BddNode2 ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (i0 and (not i1)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem *)0 ); destroybddcircuit( (bddcircuit *)0 ); SEE ALSO bdd(1) ASIM/LIP6 October 1, 1997 IMPLYBDDNODE(3)
