It implements most methods for Message Based communication over GPIB, USB, Serial, and Ethernet in a simulated environment, allowing you to develop and test instrument control code on any machine without hardware. The behavior of simulated devices is controlled by a plain text configuration file, making it easy to model different instrument responses.\n\nThe package has been actively maintained since 2015, supports Python 3.10 through 3.13, and integrates seamlessly with PyVISA's dynamic backend loading system. It's particularly useful for CI/CD pipelines, offline development, and testing measurement scripts before deploying them to real hardware.","worth_installing":"Yes. PyVISA-sim fills a genuine gap for developers working with VISA-based instrument control: it eliminates the friction of installing NI-VISA and acquiring hardware just to test code. The package is actively maintained, has no known vulnerabilities, carries a permissive MIT license, and installs with minimal friction. Install it if you work with PyVISA and need to test offline or in automated environments."},"id":"pyvisa-sim","links":{"html":"https://skillfed.io/packages/pyvisa-sim","md":"https://skillfed.io/packages/pyvisa-sim.md","pypi":"https://pypi.org/project/pyvisa-sim/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-09-04","license_spdx":null,"license_treatment":"permissive","name":"PyVISA-sim","python_support":"supports_current","summary":"Simulated backend for PyVISA implementing TCPIP, GPIB, RS232, and USB resources"},"popularity":{"monthly_downloads":188131,"position":9952,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.7.1"}
