NAME
       bddToAblCct - converts a BDD into an ABL within a circuit

SYNOPSYS
       #include "logmmm.h"
       chain_list *bddToAblCct(pC,pBdd)
       pCircuit pC;
       pNode pBdd;

PARAMETERS
       pC                  Circuit in which is made the conversion

       pBdd                BDD to convert

DESCRIPTION
       bddToAblCct() converts pBdd into an expression. This function returns a
       result that depends from the ordering of the primary input. This
       function provides the basic method for the logical optimizer called in
       BOP.

EXAMPLE
       #include "mutnnn.h"      /* mbk utilities */
       #include "logmmm.h"
       chain_list *expr;
       pNode res;
       pCircuit pC;

       initializeBdd(SMALL_BDD);
       pC = initializeCct("circuit 1",10,10);

       addInputCct(pC,"a");
       addInputCct(pC,"b");

            /* let's suppose that res = (OR a b) */

       expr = bddToAblCct(pC,applyBinBdd(OR,
                           createNodeTermBdd(searchInputCct(pC,"a"))),
                           createNodeTermBdd(searchInputCct(pC,"b")));
       displayExpr(expr);

       /* it will display
       (OR a b)
       */

       destroyCct(pC);
       destroyBdd(1);
