WebOct 8, 2024 · In LTspice you can only define 1 ground node, this is the reference voltage from where LTspice starts to calculate. If i want to use a second ground i have to use the COM node. I tried to do this but it still doesn't work. I know my mosfet part works and i know my opto coupler part works. When i try to connect both LTspice starts to behave strange.

WebSep 23, 2024 · If you are wanting to create, for example, separate "grounds" for Digital, Analog, and Earth grounds, the simplest and most compatible way is to use the "Label Net" function. So one of your ground nodes would use the standard symbol, and it would be Node 0 for LTspice. For a different "ground" you would just create a wire pointing down … WebHistorically "numdgt" was used to set the number of significant figures used for output data. In LTspice, if "numdgt" is set to be > 6, double precision is used for dependent variable data. pivrel. Num. 1e-3.

You can put it where you like, but in some places the simulation may slow down due to the increased amount of 'above/below ground' activity. Generally it is best to put it where the real ground will be in your circuit. You should choose real components (eg. building a laminate countertop
