It includes a simulator, build system, and standard library, covering the full FPGA development workflow. The language aims to reduce common hardware design mistakes and support reusable component design. Amaranth can target any FPGA or ASIC process accepting behavioral Verilog-2001, with extended support for Lattice (iCE40, MachXO, ECP5, Nexus), AMD (Virtex, Spartan, 7-series, UltraScale), Altera, and Quicklogic families. Existing Verilog or VHDL code can be integrated into an Amaranth design flow, and vice versa. The toolchain is actively maintained and supported by LambdaConcept, ChipEleven, and Chipflow.","worth_installing":"Yes. Amaranth is actively maintained, has low install friction, permissive licensing, and fills a genuine niche for developers who prefer Python for hardware design. It's suitable for anyone targeting FPGAs or ASICs who wants to avoid Verilog/VHDL syntax and leverage Python's expressiveness. No known security vulnerabilities. The main prerequisite is familiarity with digital logic and access to external synthesis toolchains."},"id":"amaranth","links":{"html":"https://skillfed.io/packages/amaranth","md":"https://skillfed.io/packages/amaranth.md","pypi":"https://pypi.org/project/amaranth/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-16","license_spdx":null,"license_treatment":"permissive","name":"amaranth","python_support":"supports_current","summary":"Amaranth hardware definition language"},"popularity":{"monthly_downloads":81776,"position":14201,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.5.9"}
