![]() ![]() ![]() It is used at various universities internationally for research and teaching. MacSpice has native support for both PowerPC and Intel architecture Apple Macintosh computers. It is derived from, and compatible with, Berkeley Spice 3f5. MacSpice incorporates many improvements to Spice 3f5 – from simple bug-fixes to entirely new commands, algorithms and solution strategies. For example: the memory leaks that affected Spice 3f4 have been cured new algorithms have been developed to facilitate the simulation of large circuits, and to reduce simulation time MacSpice provides a robust multi-parameter optimizer and facilities for inter-process communication with other applications.Ĭircuit 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.Ī 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. 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. Why does MacSpice require netlists and not have graphical schematic entry? 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. ![]() * Magic VLSI Editor (Compiles for X Windows under Xdarwin) * Electric VLSI Design System (Open Source) If you need schematic capture, you may wish to consider: MacSpice is a Spice simulator, not a schematic capture application. * xcircuit (Open Source) also available as MacPorts or Fink packages #Macspice open file windows# ![]()
