NAME
intersectbddnode - tests for an intersection between two bdd nodes.
SYNOPSYS
#include "bdd101.h" bddnode ∗intersectbddnode( 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
intersectbddnode tests if the intersection of BddNode1 and BddNode2 exists, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.
RETURN VALUE
intersectbddnode 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_AND, createablatom( "i0" ), createablatom( "i1" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); Expr = createablbinexpr( ABL_OR, createablatom( "i0" ), createablatom( "i1" ) ); BddNode1 = addbddcircuitabl( BddCircuit, Expr ); freeablexpr( Expr ); BddImply = intersectbddnode( (bddsystem ∗)0, BddNode1, BddNode2 ); Expr = convertbddcircuitabl( BddCircuit, BddNode ); /* displays (i0 and i1)) */ viewablexpr( Expr, ABL_VIEW_VHDL ); freeablexpr( Expr ); destroybddsystem( (bddsystem ∗)0 ); destroybddcircuit( (bddcircuit ∗)0 );
