digsim-native
The native simulation engine of DigSim, in Rust
(PyO3). DigSim uses it when it can import digsim_native, and simulates in Python when
it can't. Both engines give the same results, the native one about 10x faster on Yosys
netlists.
Install
The wheels are on the releases, one per platform for every Python from 3.11: Linux x86_64 and aarch64 (glibc and musl), Windows x64 and arm64, macOS arm64 and x86_64.
pip install digsim-native==0.1.0 \
--find-links https://github.com/freand76/digsim-native/releases/expanded_assets/v0.1.0
DIGSIM_ENGINE=python python ... # the Python engine, with the package installed
What it does
Rust runs the event loop and simulates every Yosys gate and functional cell, GND, VDD,
the bus ports up to 64 bits and one-bit ports with several drivers. Every other component
stays in Python and is called from the same event queue. When the wires change during a
simulation, the engine hands its state back to Python until the next init().
Build
pip install maturin
maturin build --release # the wheel, in target/wheels/
pip install target/wheels/*.whl # into the environment of DigSim
cargo fmt --check && cargo clippy --release -- -D warnings
The tests are in DigSim (its pytest, and tools/native/).
Releases
- Bump
versioninCargo.tomlandpyproject.toml, and the pin in DigSim. - Push a tag
vX.Y.Z. TheWheelsworkflow builds and tests the wheels and attaches them to a release.
The interface to DigSim isn't stable, so DigSim pins the version it was written for.
