# YosysHQ/yosys

> Yosys is an open-source RTL synthesis framework supporting Verilog-2005 and a synthesizable subset of SystemVerilog. It converts HDL descriptions into netlists and optimizes digital logic.

- Magnitude: 0.9 out of 10 — Quiet
- Stars: 4,853 total · +1 star measured 2026-10-29, 00:11–05:50 UTC, ≈ 2 by evening
- Star trust: star growth looks organic

## Useful for

- Synthesize a Verilog project into a netlist for FPGA implementation.
- Run formal verification of an HDL design using SBY.
- Extend Yosys with custom synthesis passes in C++.

## Why it’s here

- Star-counter measurements on 2026-10-29 (UTC), 00:11–05:50: 4852 → 4853 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +2 stars, using observed gains and the previous day.
- Recent forks include notable developers: @pavel-kirienko (251 followers).

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1,193
- Issues and pull requests: 6,113
- Watchers: 124
- Average over the last week: 4 per day
- Usual pace: 2 per day
- Stars in the last hour (measured): 0

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
Data as of 2026-10-29 05:52 UTC, updated every 30 minutes.
