7  Synopsis    [Flat network of multi-valued combinational nodes and latches.]
8
9  Description [A network is a directed graph, where the vertices are nodes (of
10  type Ntk_Node_t) and the edges are stored as fanin and fanout arrays of each
11  node.  Each node has a single output, which may fanout to multiple nodes. A
12  node is one of 5 types.  In addition, it may have one or more optional
13  attributes, respecting the following table:
14
15  <pre>
16    type         |             attributes
17  ---------------+-------------------------------------------
18                 | primary  latch data  latch init  constant 
19                 |  output    input        input             
20  ---------------+-------------------------------------------
21  pseudo input   |   x          x            x               
22  primary input  |   x          x            x               
23  latch          |   x          x           
24  shadow         |                           
25  combinational  |   x          x            x         x
26 
27  Legend:
28    primary input:    a node with no fanins that is a port of the network;
29                      does not have a table defining its function - it can
30                      take any value in its domain
31    pseudo input:     a node with no fanins, introduced to model
32                      nondeterminism; its table defines which values it can
33                      take
34    latch:            an edge triggered latch with data and initial inputs
35    shadow:           a node with no fanins and no fanouts; it serves as a
36                      "shadow" for a node; for example, a shadow node for a
37                      latch is used to store information about the next
38                      state variable; any node can have a shadow, except a
39                      shadow node
40    combinational:    a node that has a table and is not a primary or pseudo
41                      input
42
43    primary output:   a node that is a port of the network
44    latch data input: a node driving the data input of a latch
45    latch init input: a node driving the initial input of a latch
46    constant:         a combinational node with no fanins that can take
47                      exactly one value
48  </pre>
49
50  An "x" in the table means that it's permissible for a node of the given type
51  to have the given attribute; the absence of an "x" means it's not
52  permissible.<p>
53 
54  In addition, there are several derived attributes: all primary inputs,
55  pseudo inputs, and latches are "combinational inputs"; all latch data
56  inputs, latch initial inputs, and primary outputs are "combinational
57  outputs"; all primary inputs and pseudo inputs are "inputs".<p>
58 
59  Each combinational node has a table defining the function of the node in
60  terms of its immediate fanins.  This function must be deterministic
61  (i.e. for a given valuation of the fanins, the function can assume at most
62  one value) and completely specified (i.e. for a given valuation of the
63  fanins, the function can assume at least one value) in order to ensure
64  correctness of verification results downstream .  (The exception is that
65  pseudo inputs are nondeterministic.)  The table may have multiple output
66  columns, so the node keeps an index giving the output column to which it
67  refers.<p>
68 
69  The ntk package contains facilities to create a network (Ntk_Network_t) from
70  a hierarchical network.  In particular, it supports the concept of "actual
71  names" and "formal names". Consider the following hierarchical network:
72  <pre>
73             +--------------------+
74             |  A                 |
75             |                    |
76             |  +-----+    +----+ |
77             |  | B   |    | C  | |
78             |  |     |    |    | |
79             |  |   x |  y | z  | |
80             |  |  ---+----+--  | |
81             |  |     |    |    | |
82             |  +-----+    +----+ |
83             |                    |
84             +--------------------+
85  </pre>
86  This is meant to depict a block A that contains two blocks B and C.  There
87  is a wire originating in block B, passing through block A, and terminating
88  in block C.  This wire has three different names, A.y, A.B.x, and A.C.z,
89  depending on from which block it is viewed. When a hierarchical network is
90  flattened into a Ntk_Network_t, each node is assigned a unique name,
91  referred to as the "actual name".  The actual name is the name with the
92  fewest levels of hierarchy in it (in this example, A.y).  All other names
93  are referred to as "formal names" (in this example, A.B.x, and A.C.z).  The
94  following functions deal with actual and formal names: Ntk_NodeReadName,
95  Ntk_NetworkFindNodeByActualName, Ntk_NetworkReadActualNameFromFormalName,
96  Ntk_NetworkInsertFormalNameToActualName, Ntk_NetworkFindNodeByName.  See the
97  function descriptions for more details.<p>
98
99  A network may have an MDD manager associated with it, and the nodes may have
100  MDD ids.  However, the network itself does not keep track of any MDDs.  This
101  is the job of the partition package.]
