| 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.] |
