Load a macspice file10/29/2023 New models can be added to the simulator using: The implementation of the node is created and simulated by using C language with macros which is compiled by standard C/C++ compilers. Ngspice provides an internal scripting language to facilitate complex simulation and evaluation control flows.įor mixed signal circuit simulation ngspice allows users to create a user-defined node definition file (UDN) of a new device model interface. PSPICE compatible parametric macromodels, often released by manufacturers, can be imported as-is into the simulator. netlists can contain parameters and expressions). Ngspice supports parametric netlists (i.e. Ngspice implements various circuits elements, like resistors, capacitors, inductors (single or mutual), transmission lines and a growing number of semiconductor devices like diodes, bipolar transistors, MOSFETs (both bulk and SOI), MESFETs, JFETs and HFETs. Small-Signal distortion analysis and frequency response analysis (AC).Operating point sweep analysis - determines the values of output variables while one or two specified independent voltage or current source is stepped over. Operating point analysis - determines the dc operating point of the circuit with inductors shorted and capacitors opened.AC analysis includes small-signal noise simulation, pole-zero and transfer function analysis: Transient analysis includes transient noise simulation. Ngspice implements three classes of analysis: Critical devices can be described with their technology parameters (numerical models), all others may use the original ngspice compact models. It couples the circuit-level simulator to the device simulator to provide enhanced simulation accuracy (at the expense of increased simulation time). Cider adds a numerical device simulator to ngspice.Xspice is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.SPICE is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community.Ngspice is based on three open-source free-software packages: Spice3f5, Xspice and Cider1b1: A small group of maintainers and the user community contribute to the ngspice project by providing new features, enhancements and bug fixes. It is a successor of the latest stable release of Berkeley SPICE, version 3f.5, which was released in 1993. Ngspice is an open-source mixed-level/ mixed-signal electronic circuit simulator. net /projects /ngspice /files /ng-spice-rework /
