I spent about 2 hours trying to find out that I simply needed to number the ground node zero!! Let’s start with the voltage supply. Let’s start with a much simpler circuit we’ll ditch both transistors and represent the motor as a simple resistor, tying it directly to 9V and GND. The description file lists each of the components, and what nodes the components are connected to. The MacSpice website has good documentation: Tutorials and User Guide I found the following websites helpful, too: First I have to draw the old motor circuit. I want to use modeling to analyze the existing circuit and to help me come up with a better design. Revisiting Pokey’s Fan Motor Circuit: You may recall the crappy, last minute, motor driver circuit I threw together for Pokeymy firefighting robot. The tool remains text based, but with some menu wrappers for a few titorial.
You can model numerous devices and print and plot the results of the simulation. It can do transient analysis, steady-state, AC small signal analysis, DC transfer function analysis.

Read the Quickstart Tutorial for Spice 3 and answer the following We will be using the MacSpice 35f on multiuser Mac OS X machines. Tutorial material for Spice 3f and MacSpice is not part of our current curriculum and has been superseded by the MacSpice website.
