Hi is the equivalent circuit generated by Fasthenry which is spice3 compatible file also compatible with LTspice? i have generated the equivalent circuit of a Simulation i ran, but i cant include it in LTspice.
In general FastHenry2 circuits are compatible with LTSpice, both the ones generated with makeLcircuit.exe and the Reduced Order Models (ROM).
However, without indications about the equivalent circuit and / or the error you get when you try to include it in LTSpice, it is not easy to answer you.
