implybddnode3

Synopsys

#include "bdd101.h"
bddnode ∗implybddnode( BddSystem, BddNode1, BddNode2 )
  bddsystem ∗BddSystem;
  bddnode   ∗BddNode1;
  bddnode   ∗BddNode2;

Parameters

Overview

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.
