MacSpice Description

Spice-compatible simulator for Mac OS X As its name suggests, MacSpice is an implementation for the Mac of the Berkeley Spice 3f5 electronic circuit simulator. However, MacSpice is not merely a 'port' of the Berkeley code, it incorporates many improvements ranging from bug-fixes to entirely new graphics, algorithms and solution strategies. Spice is not easy to use, but it is a powerful tool once the initial hurdles have been overcome and the MacSpice website provides support and tutorials.SPICE is a general-purpose circuit simulation program for nonlinear dc, nonlinear transient, and linear ac analyses.Circuit simulation is a way of building and testing virtual models of electronic devices. It is usually cheaper and quicker to simulate a design than to build a prototype. MacSpice, like most circuit simulators, requires a text-file description of the circuit as input. This 'netlist' is a list of components and the nodes they connect to. Users may prepare netlists with a text editor, or derive them from a circuit diagram using a third-party schematic-capture application. MacSpice then builds a numerical model of the circuit and analyses this.A command interpreter (shell) is used to specify the types of analyses that are required and how the results should be processed, saved or displayed. The high quality of the MacSpice command interpreter makes the automation of tasks straightforward.Simulation is a tool, not a magic-wand. The quality of the results depends on the accuracy of the netlist and the device models use. Within Spice most devices are ideal its resistor, for example, has just one property: resistance. A real resistor has parasitic inductance and capacitance; if these have a significant influence on the circuit, they must be added explicitly to the netlist. Requirements: · TextWrangler What's New in This Release: Enhancements: · HiSIM_HV model updated to version 1.2.0 (level=62). · Improved convergence for some types of 'B' source devices. · Improved tick label format for linear graph axes when 'xdelta' and/or 'ydelta' are specified. · Spice-2 'poly' sources accept node names containing symbols like '+' and '-'. · New warning for netlist lines that are ignored because they have leading whitespace. Bugs fixed: · Explicit 'save all' is not deleted by subsequent 'save' statements. · Evaluating '@v1' no longer crashes if 'coeffs' is an empty list. · Typing a single '$' at the command line no longer causes a freeze.
