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. This is true for whichever SPICE program that uses those nodes as floating nodes. In this article well provide an overview of AC and DC simulation. Ltspice Mac Ground In order to setup the folders properly, the ltspiceexample folder needs to be copied to the projects/examples folder in EAGLEs installation directory.
It, too, needs to be referenced to ground, so some connection is needed, if you so choose to use it. LTSpice is a versatile, accurate and free circuit simulator available for Windows and Mac. LTspice is an extremely valuable tool for designing and simulating analog based circuits. 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. This circuit simulation which is compatible for PowerPC and Intel architecture.

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). Click the Download for Mac OS X 10.7+ button within the Download LTspice section of the homepage to download the LTspice.dmg file. MacSpice is a free circuit simulation software for Apple Macintosh users. 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. And all nets can be renamed to whatever name/label/etc is needed. 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.
