implybddnode.3alc - Man Page
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, exists, 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 );
