SYNOPSYS

#include "bdd101.h"
bddnode *simpbddnodedcoff( BddSystem, BddOff, BddDc )
  bddsystem *BddSystem;
  bddnode   *BddOff;
  bddnode   *BddDc;

PARAMETERS

BddSystem

The bdd system.

BddOff

The first bdd node.

BddDc

The second bdd node.

DESCRIPTION

simpbddnodedcoff simplifies the bdd node BddOff 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 off-set part of the bdd node BddOff.

RETURN VALUE

simpbddnodedcoff returns the simplified bdd node.
