General Purpose Schematic Driven SPICE

This is the main use of the LTspice XVII simulator. Within the restrictions found in the license, you are free to use LTspice XVII as your general-purpose schematic capture/SPICE program even for circuits which do not use Linear Technology products. Many companies standardize on LTspice as their EDA tool.

LTspice XVII allows you to draft and simulate circuits of unlimited size and content. Marching waveforms, cross probing, reverse cross probing, and unlimited hierarchy are supported.
