constraintBdd(3)

NAME

constraintBdd - restricts a BDD to another BDD

SYNOPSYS

#include "logmmm.h"
pNode constraintBdd(pBdd1,pBdd2)
pNode pBdd1;
pNode pBdd2;

PARAMETERS

pBdd1: BDD to restrict

pBdd2: constraint BDD

DESCRIPTION

constraintBdd() constructs the graph for the function obtained by restricting pBdd1 on pBdd2. This function can be used for example when a primary input is stuck at 0 or 1.

EXAMPLE

#include "mutnnn.h"		/* mbk utilities */
#include "logmmm.h"
pNode nodeA,nodeB;
pNode res;
initializeBdd(SMALL_BDD);
nodeA = createNodeTermBdd(3);
nodeB = createNodeTermBdd(3);
res = applyBinBdd(OR,nodeA,nodeB);	/* res = (OR a b)
res = constraintBdd(res,nodeA);		/* a = 1 */
displayBdd(res,1);
/* it will display 
@res   ONE 
*/
destroyBdd(1);
