There is a comprehensive set of documentation, tutorials and examples for MacSpice at You can also email for additional advice and support. In practice it is easier to identify the sources representing the power supplies, and just sum the reported dissipation for these. These need to be excluded from the calculation. However, many so-called macro models for devices use virtual sources (and other components) as part of the model. The problem is that the SPICE2 method is okay for simple circuits where adding up the the power supplied by every source is what you want. The netlist describes a low-pass RC-filter driven by a voltage source. There are some more advanced examples elsewhere on this site. Something that people sometimes miss with Spice 3 is the automatic calculation of the power dissipation of a circuit which SPICE2 used to produce. The netlists and scripts on this page are straightforward examples that users of MacSpice 3, and other Spice-compatible simulators may refer to and adapt. control/.endc lines, or in a script file. These commands can be stored with the netlist between. Circuit_spice3.src file ends above this line -ДЄnd then type the following commands at the command line:Д®tc. Circuit_spice3.src file starts below this line. To get the results you seek using the Spice 3 as nature intended use: For example: the memory leaks that affected Spice 3f4 have been cured.

Since VT220s could only display 24 lines of 132 characters with no scroll-back having large amounts of data spew out by default was counterproductive so, by default Spice 3 does nothing until asked. Download the latest version of MacSpice for Mac - Electronic circuit simulator. It was also possible to run (small) simulations interactively in a matter of minutes.

You can also provide your own sample code review ratings and comments by selecting the write option at the bottom of the Sample Code Reviews screen. On the sample code search results, you can click on the Read Review link to see detail about how others rate the code.

Circuit_spice2.src file ends above this line -Д«y 1989, when Spice 3 came out, most people would have used a terminal such as a VT100 to review the results of simulations. Code is made available after a high-level review by our team. Circuit_spice2.src file starts below this line.

So, here is how to make MacSpice (roughly) reproduce this behaviour: One was expected not to waste a second of precious CPU time so by default it produced a dump of everything onto a bail of line-printer paper to study while waiting for the next place in the queue. At that time circuit simulation was typically performed by feeding punched cards into a mainframe and waiting many hours. I use MacSpice, which is a fairly straightforward port of Berkeley Spice 3f5. This was a fortran version of Spice released in 1983. Code Examples Popular Software Downloads.

Which is using SPICE2.6G for its examples.
