DOWNLOAD IT TRY IT OUT THEN REGISTER IT!		Welcome 5Spice offers easy to use analog circuit simulation for the typical circuit designer. 5Spice provides Spice specific schematic entry, the ability to define and save an unlimited number of analyses and integrated graphing of simulation results. Plus easy inclusion of Spice/PSpice® subcircuits from a user expandable library. The focus is on analog circuit analysis and circuit design at the component level. Student level MOSFET IC design is also supported but not compatible with HSpice® model libraries. 5Spice provides the analysis capabilities needed by experienced circuit designers while remaining easy to use - a big step up from student oriented Spice programs. October 17, 2008     VERSION 1.50 Network License Upgrade: get credit for existing licenses when you purchase by December 31. more information Features most Spice concepts are represented visually in the schematic use a wizard to set Spice simulation defaults to match your circuit define, name and save unlimited numbers of analyses, each with a corresponding graph indexed library of Spice models and subcircuits - easily add manufacturer's files of models and subcircuits or your own. Accepts Spice3 subcircuit syntax plus significant compatibility with PSpice® subcircuit syntax (as used by Analog Devices, Linear Technology and TI). Not compatible with PSpice digital models. the opamp and generic subcircuit schematic symbols adjust the number of pins to match the number of nodes in the subcircuit. users can enter names for the pins which are then saved in the library. temperature or component values can be swept and results plotted in a single graph. an included opamp model allows opamp GBW to be swept. no need to keep track of circuit node numbers when graphing support for analysis of alternative designs much of Spice's traditional quirkiness is hidden from the user program's Help tells how to perform tasks, written by a Spice user behavioral modeling: schematic symbol with user defined equation (equation may contain IF-THEN-ELSE structures, math functions, etc.) program's self-documentation capability allows designers to rapidly return to their work after months off Features when you register the program adds larger schematic sizes (standard A,B,C drawing sizes). drawing size in the unregistered program is about half of A size. program licensed for use in business and government. the unregistered program allows this use only for a 30 day evaluation period. remove promotional text in schematic found in unregistered program, add user's company information to title box. Noise, AC and DC Sensitivity analysis - view results FFT and large signal harmonic Distortion analysis (Fourier Transform based) - view results pass parameter values from schematic symbol to its subcircuit save schematics containing logic gates, flip flops, one-shot save schematics containing Transformer with saturating core export tabular data from graph/table to file for import into another program priority in obtaining support and more support options Philosophy As shareware, 5Spice depends on feedback from its users for bug detection and product improvement ideas. And to pass the word. Watch the site for updated versions. Program written by an electrical engineer - see Design Consulting page. Platform Windows 2000, XP or Vista running on a Windows compatible computer. Should run in Windows on Macintosh computers that have an Intel processor but we do not support this environment. Pentium class processor or equivalent. 256 colors or higher. 800x600 or higher screen resolution recommended. Simulation speed proportional to processor speed. Program does not work in countries where Windows displays a negative number as (12) or as 12- To find out more See the other pages of this site.
