static DdNode* addBddDoStrictThreshold	(	DdManager *	dd,
		DdNode *	f,
		DdNode *	val
	)

static

◆ addBddDoThreshold()

static DdNode* addBddDoThreshold	(	DdManager *	dd,
		DdNode *	f,
		DdNode *	val
	)

static

Performs the recursive step for Cudd_addBddThreshold.

Returns: a pointer to the BDD if successful; NULL otherwise.

Side effects None

See also: addBddDoStrictThreshold

◆ Cudd_addBddInterval()

DdNode* Cudd_addBddInterval	(	DdManager *	dd,
		DdNode *	f,
		CUDD_VALUE_TYPE	lower,
		CUDD_VALUE_TYPE	upper
	)

Converts an ADD to a BDD.

Replaces all discriminants greater than or equal to lower and less than or equal to upper with 1, and all other discriminants with 0.

Returns: a pointer to the resulting BDD if successful; NULL otherwise.

Side effects None

See also: Cudd_addBddThreshold Cudd_addBddStrictThreshold Cudd_addBddPattern Cudd_BddToAdd

◆ Cudd_addBddIthBit()

DdNode* Cudd_addBddIthBit	(	DdManager *	dd,
		DdNode *	f,
		int	bit
	)

Converts an ADD to a BDD by extracting the i-th bit from the leaves.

Converts an ADD to a BDD by replacing all discriminants whose i-th bit is equal to 1 with 1, and all other discriminants with 0. The i-th bit refers to the integer representation of the leaf value. If the value has a fractional part, it is ignored. Repeated calls to this procedure allow one to transform an integer-valued ADD into an array of BDDs, one for each bit of the leaf values.

Returns: a pointer to the resulting BDD if successful; NULL otherwise.

Side effects None

	)

Converts an ADD to a BDD.

Replaces all discriminants different from 0 with 1.

Returns: a pointer to the resulting BDD if successful; NULL otherwise.
