LTspice IV is freeware〔Mike Engelhardt: ''LTspice IV Help → F.A.Q. → License and Distribution.'' (Help of software version 4.19u of 4 September 2013)〕〔Mike Engelhardt: ''LTspice IV Help → Introduction → License Agreement/Disclaimer.'' (Help of software version 4.19u of 4 September 2013)〕 computer software implementing a SPICE simulator of electronic circuits, produced by semiconductor manufacturer Linear Technology (LTC).〔(LTspice IV Circuit Simulation Schematic Capture Tool )〕 ==Overview== LTspice IV provides a schematic capture and waveform viewer with enhancements and models to speed the simulation of switching regulators. Supplied with LTspice IV are macro models for 80% of LTC's switching regulators and operational amplifiers, transistors, MOSFETs, and passive components. LTspice IV is node-unlimited and third-party models can be imported. Circuit simulations based on transient, AC, noise and DC analysis can be plotted as well as Fourier analysis. Heat dissipation of components can be calculated and efficiency reports can also be generated. LTspice IV is used within LTC, and by many users in fields including radio frequency electronics, power electronics, digital electronics, and other disciplines. LTspice IV does not generate printed circuit board (PCB) layouts, but netlists can be imported into layout programs. LTSpice IV can't simulate a complex digital logic. LTspice was originally called SwitcherCAD and is sometimes still called by that name. The software is maintained by Mike Engelhardt. The application is written for Microsoft Windows but, since 2003,〔(news:sci.electronics.cad: LTspice/SwitcherCAD III now runs on Linux ) accessdate=September 27, 2013〕 it will run under the Wine Windows simulator under Linux. Since 2013 there is also a native OS X version available. From version IV LTspice requires at least a Pentium 4 processor and Windows 2000 or later.〔(news:sci.electronics.cad: Announce: Multi-threaded LTspice ) accessdate=September 27, 2013〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LTspice」の詳細全文を読む スポンサード リンク
