.SH NAME
\fBsimplifDcZeroBdd\fP \- simplifies a BDD with don't cares on its off-set part
.SH SYNOPSYS
.nf
#include "logmmm.h"
pNode simplifDcZeroBdd(pBdd1,pBdd2)
pNode pBdd1;
pNode pBdd2;
.fi
.SH PARAMETERS
.TP 20
\fIpBdd1\fP
BDD to simplify
.TP 20
\fIpBdd2\fP
"don't care" function
.SH DESCRIPTION
\fBsimplifDcZeroBdd()\fP simplifies \fIpBdd1\fP with \fIpBdd2\fP. \fIpBdd2\fP must be included imperatively in the off-set part of pBdd1. This function returns a BDD that depends to the order of the BDD.
.SH EXAMPLE
.nf
#include "mutnnn.h"		/* mbk utilities */
#include "logmmm.h"
pNode nodeA,NodeB;
pNode res,res1,res2;

initializeBdd(SMALL_BDD);
nodeA = createNodeTermBdd(3);
nodeB = createNodeTermBdd(3);
res1 = applyBinBdd(OR,nodeA,nodeB);	/* res1 = (OR a b) */
res2 = applyBinBdd(NOR,nodeA,nodeB);	/* res2 = (NOR a b) */
res = simplifDcZeroBdd(res1,res2);	/* res1 and res2 = 0 */
displayBdd(res,1);

/* it will display 
@res   ONE 
*/
