NAME

       simpbddnodedcoff - simplifies a bdd with don't cares on its off-set part.

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.

          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
