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);
