In practice it is easier to identify the sources representing the power supplies, and just sum the reported dissipation for these. It allows you to generate a code model in a library to be loaded into ngspice and to use the powerful debugger offered by MS Visual Studio in a step by step mode. These need to be excluded from the calculation. This circuit simulation which is compatible with PowerPC and Intel architecture. However, many so-called macro models for devices use virtual sources (and other components) as part of the model. MacSpice is a free circuit simulation software for Apple Macintosh users. 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. Something that people sometimes miss with Spice 3 is the automatic calculation of the power dissipation of a circuit which SPICE2 used to produce. control/.endc lines, or in a script file. The free demo mode is all that is needed for use with MacSpice. These commands can be stored with the netlist between. Download, install and launch BBEdit from here. Circuit_spice3.src file ends above this line -Īnd then type the following commands at the command line:Įtc. Circuit_spice3.src file starts below this line. To get the results you seek using the Spice 3 as nature intended use: 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. It was also possible to run (small) simulations interactively in a matter of minutes. Circuit_spice2.src file ends above this line -īy 1989, when Spice 3 came out, most people would have used a terminal such as a VT100 to review the results of simulations. Circuit_spice2.src file starts below this line - Mace spice is found in recipes for cobblers, donuts, pumpkin pie, and some eggnog recipes to create the perfect blend of sweet and spicy. 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. This was a fortran version of Spice released in 1983. It provides an enhanced versions of the Spice 3 simulator and the Nutmeg front-end command interpreter. Which is using SPICE2.6G for its examples. MacSpice is distributed as a Mac OS X application bundle.
