SYNOPSYS

#include "bdd101.h"
bddnode *simpbddnodedcon( BddSystem, BddOn, BddDc )
  bddsystem *BddSystem;
  bddnode   *BddOn;
  bddnode   *BddDc;

PARAMETERS

BddSystem

The bdd system.

BddOn

The first bdd node.

BddDc

The second bdd node.

DESCRIPTION

simpbddnodedcon simplifies the bdd node BddOn with BddDc, in the bdd system BddSystem. If a null pointer is given, the default bdd system is used. The bdd node BddDc must be included imperatively in the on-set part of the bdd node BddOn.

RETURN VALUE

simpbddnodedcon returns the simplified bdd node.
