5Spice
5Spice is a new graphical user interface that wraps around a traditional Spice simulation engine, presenting a single application to the user. It 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, integrated graphing of simulation results plus easy inclusion of Spice/PSpice subcircuits from a user expandable library. The program's self-documentation capability allows designers to rapidly return to their work after months off. 5Spice provides the analysis capabilities needed by experienced circuit designers while remaining easy to use - a big step up from student oriented Spice programs. The focus is on analog circuit analysis and circuit design at the component level. Student level MOSFET IC design is also supported.
Features
most Spice concepts are represented visually in the schematic
no need to keep track of circuit node numbers when graphing
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.
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.)
