7  Synopsis    [Partition of a system and creation of MDDs.]
8
9  Description [Once the description of a system has been read, and the ordering
10  of the variables has been assigned, the partition package creates an
11  abstracted view of the system in which only information in terms of MDDs is
12  stored. The MDDs belong to the MDD manager of the system. Different options
13  may be considered when creating this abstracted view. If the system is
14  described as a network there are several options to create this partition. As
15  a first choice, the system may be considered as a set of functions
16  representing the combinational outputs as functions of the combinational
17  inputs. In general, the latch functions may be specified as functions of any
18  intermediate variables. These intermediate variables are themselves functions
19  of other variables, and ultimately the dependency on the combinational inputs
20  is achieved. The structure to represent these arbitrary dependencies is a
21  DAG. The combinational inputs of the network will be represented as
22  vertices. Every other function (either representing a latch or any other
23  intermediate node) is represented as a vertex with in-coming edges from the
24  vertices representing the function's domain. Hence, the vertices representing
25  the combinational inputs will not have any in-coming edges, and conversely,
26  the vertices representing the combinational outputs will not have any fanout
27  edges.<p>
28
29  The partition may have two types of vertices, called single and
30  clustered. Single vertices are the ones that represent, for example, nodes in
31  a network. Clustered vertices are used solely for the purpose of grouping
32  single vertices into disjoint sets. No clustered vertex can be member of a
33  clustered vertex, and every single vertex may be a member of a unique clustered
34  vertex. The edges of the graph are connecting only single vertices. Functions
35  are provided to access the list of vertices represented by a clustered vertex
36  as well as for testing the type of a vertex.<p>
37
38  A partition is the central input to the image computation
39  package.  However, it is important to note that there is no network-specific
40  information stored in the partition data structure itself.  Hence, it is
41  possible that another application (i.e. besides the network application)
42  could create a partition, and use that partition as input to the image
43  computation package.]

91  Synopsis    [Type of vertex in the partition.]
92
93  Description [There are two types of vertices in the partition: single and
94  clustered. A single vertex represents itself and it may have a multi-valued
95  function and a MddId attached to it. A clustered vertex represents a set of
96  single vertices. The only information stored in this type of vertex is the
97  list of single vertices being represented by the cluster. Only one level of
98  hierarchy is allowed, that is, clustered vertices may only represent single
99  vertices. Every single vertex may only be represented by a unique clustered
100  vertex. In other words, a vertex representing a cluster of vertices cannot be
101  a member of another cluster.]
