Function Documentation

◆ Cudd_zddCountMinterm()

double Cudd_zddCountMinterm	(	DdManager *	zdd,
		DdNode *	node,
		int	path
	)

Counts the number of minterms of a ZDD.

Counts the number of minterms of the ZDD rooted at node. This procedure takes a parameter path that specifies how many variables are in the support of the function.

Returns: the count. If the procedure runs out of memory, it returns (double) CUDD_OUT_OF_MEM.

Side effects None

See also: Cudd_zddCountDouble

◆ Cudd_zddDagSize()

int Cudd_zddDagSize ( DdNode * p_node )

Counts the number of nodes in a ZDD.

Deprecated:: This function duplicates Cudd_DagSize and is only retained for compatibility.

Side effects None

See also: Cudd_DagSize

◆ Cudd_zddPrintSubtable()

void Cudd_zddPrintSubtable ( DdManager * table )

Prints the ZDD table for debugging purposes.

Side effects None

◆ cuddZddDagInt()

static int cuddZddDagInt	(	DdNode *	n,
		st_table *	tab
	)

static

Performs the recursive step of Cudd_zddDagSize.

Does not check for out-of-memory conditions.

Side effects None
