What is LTspice used for?

LTspice® is Analog Devices’ high performance circuit simulation program, which allows you to draft, probe, and analyze the performance of your circuit design. LTspice contains an integrated schematic editor, waveform viewer, and advanced features that are easy to use once you learn some basic commands.

What does LT stand for in LTspice?

The Spice platform used to illustrate these concepts will be the freely available Spice program called LTSpice supplied by Analog Devices, Inc. The prefix LT before the word Spice stands for Linear Technologies; the name of the company that created this program before being acquired by Analog Devices, Inc (ADI).

How do I model a relay in LTspice?

You can use a voltage controlled switch to simulate the contacts (Just called SW in LTSpice). Set the operating voltage to match pull-in voltage of your relay. You can use a resistor (and an inductor if desired) to simulate the relay coil.

How do I use SW LTspice?

To insert and configure a switch in LTspice… Insert the symbol for the voltage-controlled switch in your schematic (press F2 and type “sw” in the search field of the symbol library). where “MYSW” is the unique model name, Ron and Roff are the on and off resistances and Vt and Vh are the trip and hysteresis voltages.

Is LTspice better than pspice?

Models for extreme corner cases (e.g. only Pspice as a nonlinear inductor model, Hspice has some unique MOS/BJT models for leading edge geometries, LTSpice is strictly not based on UCB SPICE 3 but the other two are, which both provides advantages and disadvantages in terms of simulation repeatability of models.

What are spice tools?

An ecodesign tool to drive sustainable packaging innovation. The SPICE Tool helps cosmetics and personal care companies embed ecodesign into the packaging development process. This intuitive tool makes robust environmental data accessible to packaging designers, empowering them to develop more resilient packaging.

Is Ltspice better than pspice?

What is a relay do?

Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. When a relay contact is Normally Closed (NC), there is a closed contact when the relay is not energized.

What is the difference between PSpice and Hspice?

difference between pspice and hspice They are made by different companies. PSpice comes with a schematic capture program and does some things automatically. It is good for casual and new users. HSpice has a wider range of user selectable options but therefore requires more user skill.

How can I model a relay In LTspice IV?

An inductor in series with the coil resistance can be useful to simulate the inductive kick the relay produces when switched off. You can use a voltage controlled switch to simulate the contacts (Just called SW in LTSpice). Set the operating voltage to match pull-in voltage of your relay.

How to create new symbols in Lt Spice?

There is no way to scale components, so it will need to be redrawn. However, if you copy an existing symbol from the LTspice symbol directory, and rename it, you can use the symbol elements, (circles, lines, rectangles etc) as a guide, to create your new component. In this example I have drawn a new symbol for an electrolytic capacitor.

Is there a simulation of a DPDT relay symbol?

I just generated a functional simulation model for a DPDT relay symbol I had previously downloaded (both attached). It includes an approximate 15ms open and close delay to simulate the mechanical relay operation. I’m posting it for others to use because I wasn’t able to locate such a model elsewhere.

Can you use LTspice to simulate any analog circuit?

LTspice contains models for most LTC power devices, opamps, and many more ADI opamp models are being added to the LTspice library (nearly 100 ADI models to date) LTspice can be used to simulate any analog circuit you can think of! ©2019 Analog Devices, Inc.
