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);
