/*
For the lack of a better name, this format is called New Data Representation (NDR).
NDR is based on the following principles:
- complex data is composed of individual records
- a record has one of several known types (module, name, range, fanins, etc)
- a record can be atomic, for example, a name or an operator type
- a record can be composed of other records (for example, a module is composed of objects, etc)
- the stored data should be easy to write into and read from a file, or pass around as a memory buffer
- the format should be simple, easy to use, low-memory, and extensible
- new record types can be added by the user as needed
The implementation is based on the following ideas:
- a record is composed of two parts (the header followed by the body)
- the header contains two items (the record type and the body size, measured in terms of 4-byte integers)
- the body contains as many entries as stated in the record size
- if a record is composed of other records, its body contains these records
As an example, consider a name. It can be a module name, an object name, or a net name.
A record storing one name has a header {NDR_NAME, 1} containing record type (NDR_NAME) and size (1),
The body of the record is composed of one unsigned integer representing the name (say, 357).
So the complete record looks as follows: { <header>, <body> } = { {NDR_NAME, 1}, {357} }.
As another example, consider a two-input AND-gate. In this case, the recent is composed
of a header {NDR_OBJECT, 4} containing record type (NDR_OBJECT) and the body size (4), followed
by an array of records creating the AND-gate: (a) name, (b) operation type, (c) fanins.
The complete record looks as follows: { {NDR_OBJECT, 5}, {{{NDR_NAME, 1}, 357}, {{NDR_OPERTYPE, 1}, WLC_OBJ_LOGIC_AND},
{{NDR_INPUT, 2}, {<id_fanin1>, <id_fanin2>}}} }. Please note that only body entries are counted towards size.
In the case of one name, there is only one body entry. In the case of the AND-gate, there are 4 body entries
(name ID, gate type, first fanin, second fanin).
Headers and bodies of all objects are stored differently. Headers are stored in an array of unsigned chars,
while bodies are stored in the array of 4-byte unsigned integers. This is important for memory efficiency.
However, the user does not see these details.
To estimate memory usage, we can assume that each header takes 1 byte and each body entry contains 4 bytes.
A name takes 5 bytes, and an AND-gate takes 1 * NumHeaders + 4 * NumBodyEntries = 1 * 4 + 4 * 4 = 20 bytes.
Not bad. The same as memory usage in a well-designed AIG package with structural hashing.
Comments:
- it is assumed that all port names, net names, and instance names are hashed into 1-based integer numbers called name IDs
- nets are not explicitly represented but their name ID are used to establish connectivity between the objects
- primary input and primary output objects have to be explicitly created (as shown in the example below)
- object inputs are name IDs of the driving nets; object outputs are name IDs of the driven nets
- objects can be added to a module in any order
- if the ordering of inputs/outputs/flops of a module is not provided as a separate record,
their ordering is determined by the order of their appearance of their records in the body of the module
- if range limits and signedness are all 0, it is assumed that it is a Boolean object
- if left limit and right limit of a range are equal, it is assumed that the range contains one bit
- instances of known operators can have types defined by Wlc_ObjType_t below
- instances of user modules have type equal to the name ID of the module plus 1000
- initial states of the flops are given as char-strings containing 0, 1, and 'x'
(for example, "4'b10XX" is an init state of a 4-bit flop with bit-level init states const1, const0, unknown, unknown)
- word-level constants are represented as char-strings given in the same way as they would appear in a Verilog file
(for example, the 16-bit constant 10 is represented as a string "4'b1010". This string contains 8 bytes,
including the char '\0' to denote the end of the string. It will take 2 unsigned ints, therefore
its record will look as follows { {NDR_FUNCTION, 2}, {"4'b1010"} }, but the user does not see these details.
The user only gives "4'b1010" as an argument (char * pFunction) to the above procedure Ndr_ModuleAddObject().
