Also, the plot shows V(2,COM), which is just a local reference for probing can be anything, really. Its value is 1g to simulate a separate, floating ground, but really it's there with the sole purpose of providing a reference to ground without which the solver cannot calculate. Note the R2 that connects the triangular shape ground ( the ground, 0, GND) to the cosmetic COM. Drag LTspice.app to the Applications folder from within the volume’s window to install the. Double-click the LTspice Installation volume to open it. Double-click the downloaded dmg file to mount the volume. In the voltage source parameters under menu item. In addition, for the AC analysis, the input voltage with which the circuit should be stimulated should be defined. The remaining parameter information should be added as required. Under Type of Sweep, the value Decade should be selected.

This is true for whichever SPICE program that uses those nodes as floating nodes. Click the Download for Mac OS X 10.7+ button within the Download LTspice section of the homepage to download the LTspice.dmg file. The x-axis in a Bode plot should have a logarithmic scale. It, too, needs to be referenced to ground, so some connection is needed, if you so choose to use it.

I am not sure if this is the same with MAC since I am using windows. In LTspice there is only one cosmetic like that, called COM, but which has the same functionality of a common node (like chassis, earth, etc, unless mentioned otherwise). With regards to the ground net, you can find it on the Tool Bar. In this case, that chassis you're looking for, in whichever SPICE software, is just a cosmetic appearance for a net/node, labeled chassis, or earth, or whatever. In this article well provide an overview of AC and DC simulation.

And all nets can be renamed to whatever name/label/etc is needed. LTSpice is a versatile, accurate and free circuit simulator available for Windows and Mac. Due to the nature of the SPICE (ever since 40+ years), the ground ( 0, GND) node is global, but just a net, like all nets.
