Function Documentation

◆ addWalshInt()

static DdNode* addWalshInt	(	DdManager *	dd,
		DdNode **	x,
		DdNode **	y,
		int	n
	)

static

Implements the recursive step of Cudd_addWalsh.

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

Side effects None

See also: Cudd_addWalsh

◆ Cudd_addResidue()

DdNode* Cudd_addResidue	(	DdManager *	dd,
		int	n,
		int	m,
		int	options,
		int	top
	)

Builds an ADD for the residue modulo m of an n-bit number.

The modulus must be at least 2, and the number of bits at least 1. Parameter options specifies whether the MSB should be on top or the LSB; and whther the number whose residue is computed is in two's complement notation or not. The macro CUDD_RESIDUE_DEFAULT specifies LSB on top and unsigned number. The macro CUDD_RESIDUE_MSB specifies MSB on top, and the macro CUDD_RESIDUE_TC specifies two's complement residue. To request MSB on top and two's complement residue simultaneously, one can OR the two macros: CUDD_RESIDUE_MSB | CUDD_RESIDUE_TC.

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

Side effects None

Parameters

dd	manager
n	number of bits
m	modulus
options	options
top	index of top variable

◆ Cudd_addWalsh()

DdNode* Cudd_addWalsh	(	DdManager *	dd,
		DdNode **	x,
		DdNode **	y,
		int	n
	)

Generates a Walsh matrix in ADD form.

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

Side effects None
