Bridge to using Berkeley-ABC with py-aiger.
Aiger <-> ABC bridge
This package currently assumes that the ABC and aigtoaig commands are installed and in the PATH. In the future, we hope to automatically include these dependencies, but currently one needs to install them on their own.
If you just need to use
aiger_abc, you can just run:
$ pip install py-aiger-abc
For developers, note that this project uses the poetry python package/dependency management tool. Please familarize yourself with it and then run:
$ poetry install
The primary entry point for using
aiger_abc is the
function which uses
abc to simplify an AIG. For example, below we
aiger_abc can be used to simplify the following inefficient
encoding of const false.
import aiger x = aiger.atom('x') f = x ^ x print(f.aig)
aag 4 1 0 1 3 2 8 4 2 2 6 3 3 8 5 7
import aiger_abc f2 = aiger_abc.simplify(f) print(f2.aig)
aag 1 1 0 1 0 2 0
Explicitly Specifying for
simplify supports explicitly specifying the
aigtoaig commands. This is useful
if you have installed them in non-standard paths
or names. E.g.,
f2 = aiger_abc.simplify(f, abc_cmd='abc', aigtoaig_cmf='aigtoaig')
