NAME

       ablToBddCct - converts an ABL into a BDD within a circuit

SYNOPSYS

       #include "logmmm.h"
       pNode ablToBddCct(pC,expr)
       pCircuit pC;
       chain_list *expr;

PARAMETERS

       pC		   Circuit in which is made the conversion

       expr		   expression to convert

DESCRIPTION

       ablToBddCct() constructs the graph that is computed from expr. This function provides the basic method for constructing	easily	the  BDDs.
       The applyBdd() function is called recursively by going through the ABL.

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 expr = (OR (AND (NOT a) b) a) */

       res = ablToBddCct(pC,expr);
       displayBdd(res,1);

       /* it will display
       @res	 INDEX = 3   LOW = @nodeA   HIGH = ONE
       @nodeA	 INDEX = 2   LOW = ZERO     HIGH = ONE
       */

       destroyCct(pC);
       destroyBdd(1);
