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:
·
Changes from previous version
· Graph cursors behave better.
· AC Sensitivity analysis now positions grid points accurately and can resume after interruption.
· Improved pole/zero analysis - negligible complex components are rounded to zero.
· Vectors use memory more efficiently.
· Better frontend performance when large numbers of vectors are in existence.
· The big_endian/little_endian flag is now implemented for rawfiles written in batch mode.
· Case-insensitive string comparisons are performed faster.
· A warning is now issued when breakpoints are being ignored, e.g. because pulse rise-times are shorter than the value of MINBREAK.
· var_free() and ctl_free() procedures re-coded to avoid potential stack overflow in extreme cases.
· Improved display of mutual inductance parameters by show.
· Improved numerical stability of interpolate() frontend function.
· Improved rusage statistics for interrupted transient simulations.
· Improved default behaviour of xd and alpha parameters for MOS3 devices.
· shift no longer causes a crash when it is given invalid arguments.
· goto $foo when $foo has no value no longer crashes.
· Cured potential history list corruption when set history = 0 is used.
Cured some minor memory leaks occurring during:
· conversion of circuit parameters to vectors;
· destruction of parse nodes referring to user-defined functions;
· tokenization of models with zero-length parameters.
· AC sensitivity analysis now works with non-linear devices.
· Correct evaluation of lists containing empty lists.
· Variables numdgt and rawprec now unset at the first attempt.
In the game you control an electical current trying to stay alive by collecting power-ups and avoiding resistors.
You steer with the mouse, its a Munchies game with a few twists.
Solve Elec is a tool with very interesting features for circuit drawing, computation of litteral formulas for any current or voltage shown in the circuit, circuit related equation verification, graph drawing and integrated help and documentation.
Analyzed circuits function in direct current and may contain usual components such as supplies, resistors, diods, transistors and amplifiers.
Here are some key features of "Solve Elec":
· draw a circuit;
· get litteral formulas for currents and voltages of the circuit;
· verify equations related to the circuit;
· draw graphs;
· browse a documentation on electricity and electronics.
Limitations:
· 10 days trial.
The following is a brief description of each screensaver module:
Impossible Cage: Displays a rotating cube whose edges cross each other in a physically impossible manner.
Circuit: Displays moving and rotating electrical components such as resistors, chips, and LEDs. You can configure the number of pieces and whether they spin as they move.
Infinite Stairs: Displays and rotates a staircase whose stairs appear to be constantly ascending.
Moebius Ants: Displays a Moebius strip with ants marching on it. Configuration options allow you to display a solid or wireframe strip and to hide the ants.
Rubik: Displays a rotating Rubiks Cube which repeatedly shuffles and solves itself. You can configure the number of random moves made when shuffling, and change the size of the cube up to 8x8x8.
By default, on multiple monitor systems only the main monitor will run the screensaver; others will be blank. If you check the "Use All Screens" checkbox which appears in each of the configuration sheets, the screensavers will run on all screens. Generally you should not run on all monitors unless all of them support OpenGL acceleration.
