One of the side buttons acts as a modifier key to access extra macros on all the other buttons, and the other side button starts a 'Drag' at the cursor position by sending e), all of which are valid for the currently active move, drag or component placement. For LTspice, I use the side buttons (normally browser navigate Forward/Back) to make must commonly used commands directly accessable without needing to click the toolbar or touch the keyboard. You could also use a gaming mouse with its OEM button utility. LTspice is a lot easier to 'drive' if you use a five button mouse + a utility like X-Mouse Button Control that lets you map macros to mouse buttons on a per application basis. Many educational simulators aimed at beginners attempt to simulate a circuit in real time which has limitations, mainly that they have to be optimised for speed, over accuracy, as everything needs to happen fast enough to respond to the user's input.įor various reasons I still use LTspice IV which has a less rich U.I than the current LTspice XVII. The circuit is designed, the simulation run and the results shown. Another thing which beginners often struggle with is, LTSpice is not a real time simulator. I think having experience with using a variety of user interfaces helps one learn to use programs such as LTSpcie, which differ from the norm.

Lots of people find LTSpice difficult to use because it's different to other Windows applications, but it didn't bother me because I've used lots of GUI software on other platforms than M$: the Acorn Archimedes when I was much younger, then Windows and later Linux. I learned most of it on my own and by opening files created by others, whether it be the examples included or those posted on forums, such as this one. I've used LTSpice for around ten years now and only recently had to RTFM. Ran simulations on a Compaq (sewing machine) Computer.Circa 1985. But not as clunky as a netlist!!!!! I was an early adopter of PSPICE. It was this forum that ultimately dragged me into the world of LTSpice and I am glad it did!!! As others have is clunky. Recently I was doing some behavioral stuff using controlled sources using table models.

I would have adopted LTSpice sooner if I had realized how to control LTSpice at a deeper level.choosing my desired MOS model and transistor characteristics (W,L, D/S areas, etc.). in 1992 when I started using the Cadence GUI.all GUI SPICE simulations thereafter. ALL of my simulations were netlist based.no GUI.until returning to work after my Ph.D.

Went to work as a chip designer and ran punched card SPICE simulations for several years until we acquired a VAX-750.

Somebody at the data center had to load the tape before my program ran. I ran my first SPICE simulation using SPICE2 via punched cards in 1977. More random thoughts and pitch for LTSpice.
