The EPFL logic synthesis libraries are a collection of open source C++ libraries for the development of logic synthesis applications. Today, there are six libraries focused on classical computing: alice, easy, kitty, lorina, mockturtle and percy. All libraries are well documented and tested. Furthermore, being header-only, the libraries can be readily used as core components in complex design automation systems, e.g., Yosys.
In this talk, I will demonstrate how simple it is to compose these libraries to create a personalized synthesis tool capable of reading a Verilog description of a circuit, building a logic network out of it, optimizing the logic network, and then map it to lookup tables of six inputs (LUT6).
The libraries: - The alice library is a lightweight wrapper for shell interfaces, which is the typical user interface for most design automation applications. It includes a Python interface to support scripting. - The lorina library is a parsing library for simple CAD file formats. - The kitty library is a truth table library for explicit representation and manipulation of Boolean functions. - The mockturtle library implements several logic network representations and logic optimization algorithms. - percy is an exact synthesis library with multiple engines to find optimum logic networks.
