.SH NAME
\fBconstraintBdd\fP \- restricts a BDD to another BDD
.SH SYNOPSYS
.nf
#include "logmmm.h"
pNode constraintBdd(pBdd1,pBdd2)
pNode pBdd1;
pNode pBdd2;
.fi
.SH PARAMETERS
.TP 20
\fIpBdd1\fP
BDD to restrict 
.TP 20
\fIpBdd2\fP
constraint BDD  
.SH DESCRIPTION
\fBconstraintBdd()\fP constructs the graph for the function obtained by restricting \fIpBdd1\fP on \fIpBdd2\fP.
This function can be used for example when a primary input is stuck at 0 or 1. 
.SH EXAMPLE
.nf
#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);
