Blocking tasks are now capital TODO (compared to non-blocking todo). Updated some of the todos. Added note about which intel synth does which families. Rename extended Yosys universe to Yosys family. Added brief text to landing page, and also a note about the restructure and where to find old docs. Moved todolist above ToC in preparation for disabling it in the config (so that it doesn't need it's own header). Fixed pdf build, was previously breaking on trying to include the svg badges.

Auxiliary libraries
|
|
===================
|
|
|
|
The Yosys source distribution contains some auxiliary libraries that are
|
|
compiled into Yosys and can be used in plugins.
|
|
|
|
.. TODO:: fill out the newer auxiliary libs
|
|
|
|
BigInt
|
|
------
|
|
|
|
The files in ``libs/bigint/`` provide a library for performing arithmetic with
|
|
arbitrary length integers. It is written by Matt McCutchen.
|
|
|
|
The BigInt library is used for evaluating constant expressions, e.g. using the
|
|
ConstEval class provided in kernel/consteval.h.

|
|
|
|
ezSAT
|
|
-----
|
|
|
|
The files in ``libs/ezsat`` provide a library for simplifying generating CNF
|
|
formulas for SAT solvers. It also contains bindings of MiniSAT. The ezSAT
|
|
library is written by C. Wolf. It is used by the sat pass (see
|
|
:doc:`../cmd/sat`).

|
|
|
|
SHA1
|
|
----
|
|
|
|
The files in ``libs/sha1/`` provide a public domain SHA1 implementation written
|
|
by Steve Reid, Bruce Guenter, and Volker Grabsch. It is used for generating
|
|
unique names when specializing parameterized modules.
|
|
|
|
.. _sec:SubCircuit:
|
|
|
|
SubCircuit
|
|
----------
|
|
|
|
The files in ``libs/subcircuit`` provide a library for solving the subcircuit
|
|
isomorphism problem. It is written by C. Wolf and based on the Ullmann Subgraph
|
|
Isomorphism Algorithm :cite:p:`UllmannSubgraphIsomorphism`. It is used by the
|
|
extract pass (see :doc:`../cmd/extract`).
