This project is (or aims to be):
-
A solution to the Problem B of the ICCAD 2016 Contest.
-
A verilog netlist parser.
-
A verilog netlist nand-synthesizer and JIT compiler, for very fast simulation.
-
A ORBDD (Ordered Reduced Binary Decision Diagrams) creation and manipulation framework. ORBDD represent combinational circuits in canonical form, that is, the ORBDDs of equivalent predicates are equal. For this reason, ORBDDs are specialy useful to check equivalence of combinational circuits.
Since the project is in its beginnings, there is not much in this section.
Testing circuits is not easy and we need more tools to do it.
Nothing much can be done yet.
Since API is not yet defined, it is not wise yet to publish it.
This projects aims to reduce the amount of depencies to the most. However it needs cmake and boost spirit 3.0 and rapidcheck. Rapidcheck is included as a git submodule.
To compile it, run the following commands:
git clone <url for this repo>
git submodule update
cmake .
make
We are using ICCAD 2015 and ICCAD 2016 inputs as benchmarks. They are carachterized in the following table:
