![]() 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. 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. These commands can be stored with the netlist between. ![]() 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. LTspice’s enhancements and models improve the simulation of analog circuits when compared to other SPICE solutions. Schematics can be probed to produce simulation resultseasily explored through LTspice’s built-in waveform viewer. #Vin macspice simulatorIt is used at various universities internationally for research and teaching. LTspice® is high performance SPICE simulator software, including a graphical schematic capture interface. It has users who range in experience from novices to retired integrated circuit designers. It was also possible to run (small) simulations interactively in a matter of minutes. MacSpice simulates and analyses electronic circuits that can range in complexity from a single resistor to an integrated circuit comprising tens-of-thousands of devices. Remove to a plate lined with paper towel. ![]() Simmer until water is evaporated and then fry the bacon until crispy. 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. Add bacon and 1/2 cup of water to a Dutch oven over medium high heat. Circuit_spice2.src file starts below this line. #Vin macspice how toSo, 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. Which is using SPICE2.6G for its examples. ![]()
