For more in-depth details and other topics, see the full ngspice manual. 2 How to Install Ngspice ngspice-manuals has a low active ecosystem. It has 0 star(s) with 0 fork(s). It had no major release in the last 12 months. It has a neutral sentiment in the developer community. ngspice-30 file contents: ngspice-30.tar.gz ngspice source code, complete, compilable with linux, ms windows, macos, others ng_adms_va.tar.gz verilog a files for bipolar and mos, modified for ngspice ngspice-30-manual.pdf ngspice-30 user manual ngspice-doc-30.tar.gz ngspice-30 user manual lyx sources ngspice-30_64.zip ms windows … It may accompany a specific ngspice release, e.g. ngspice-24 as manual version 24. If its name contains "Version xxplus", it describes the actual code status, found at the date of issue in the Git Source Code Management (SCM) tool. The manual is intended to provide a complete description of the ngspice functionality, its features, commands, NGSPICE is an open source mixed-signal circuit simulator. It is the result of combining existing SPICE features with some extra analyses, modeling methods and device simulation features. It is freely available for use in Linux and Windows. It is recommended to use Linux for NGSPICE. NGSPICE requires you to describe your circuit as a netlist.

Page 2 • NGSPICE is an open source software • NGSPICE development is open: • There exists a core team of developers that maintains the tool, • in the early days almost any contribution was included (at the price of stability), • now contributions are included after evaluation and test (at the ngspice is the open source spice simulator for electric and electronic circuits. Such a circuit may comprise of JFETs, bipolar and MOS transistors, passive elements like R, L, or C, diodes, transmission lines and other devices, all interconnected in a netlist. Normally ngspice tries to find the file in the current directory, and if it is not found then in the user's home directory. The program is being run on a terminal with mfb name term. Run in batch mode. ngspice will read the standard input or the specified input file and do the simulation. Ngspice Users Manual Version 23 Paolo Nenzi, Holger Vogt June 1, 2011
