About:
Libngspice is the official shared library version of ngspice, a popular open-source mixed-level circuit simulator. It allows developers to embed SPICE simulation capabilities directly into their own applications via a C API. This enables programmatic control over circuit analysis, making it ideal for building custom EDA tools and automated testing frameworks.
Key Features:
  • Embeddable SPICE engine via C API
  • Supports DC, AC, and transient analysis
  • Compatible with standard SPICE model libraries
  • Multi-threaded simulation support
Use Cases:
  • Integrating circuit simulation into custom EDA software
  • Automated verification of analog circuit designs
  • Educational tools for electronics engineering
Alternatives:
  • ngspice – The command-line version of the same simulator; use libngspice when you need to embed simulation within an application rather than run it interactively.
  • Qucs-S – A graphical front-end that uses ngspice; libngspice provides the underlying engine for building programmatic interfaces.
