# simplifDcZeroBdd(3)

simplifies a BDD with don't cares on its off-set part

## NAME

**simplifDcZeroBdd** - simplifies a BDD with don't cares on its off-set part

## SYNOPSYS

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

## PARAMETERS

- *pBdd1*

  BDD to simplify

- *pBdd2*

  "don't care" function

## DESCRIPTION

**simplifDcZeroBdd()** simplifies *pBdd1* with *pBdd2*. *pBdd2* must be included imperatively in the off-set part of pBdd1. This function returns a BDD that depends to the order of the BDD.

## EXAMPLE

```
#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
*/
destroyBdd(1);
```
