applybddnodeite3

Synopsys

#include "bdd101.h"
bddnode ∗applybddnodeite( BddSystem, BddIf, BddThen, BddElse )
  bddnode   ∗BddSystem;
  bddnode   ∗BddIf;
  bddnode   ∗BddThen;
  bddnode   ∗BddElse;

Parameters

Overview

applybddnodeite computes the following logical function (BddIf AND BddThen) OR ((NOT BddIf) AND BddElse) in the bdd system BddSystem. If a null pointer is given, the default bdd system is used.

Return value

applybddnodeite returns a pointer to the resulting bdd node with its number of external reference incremented.
