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);
