Spice free software

This video provides an overview of the advantages of using LTspice in an analog circuit design and how easy it is to get started. Download our LTspice simulation software for the following operating systems:. Download for Windows 7, 8, and 10 bit Version Download for MacOS View Demo Circuits. LTSpice will easily accept other spice models as Subcircuits. You need to do your home work before public commenting. Alan Bate Electronics Perhaps you should learn to read dates and do your own homework before you go around accusing other people of not doing their homework.

This article is 8 years old. All of the documentation for LTSpice that talks about adding third-party models is roughly 6 years old. Then when you were ready to use DXYZ in your schematic, you just match the component type Diode, Transistor, etc and then name it the same as your text file.

While this is similar to putting the models in a separate file, if you plan on using a lot of non-LT parts in your design, your schematic can get quite cluttered.

Harder to create high level schematics — OK, this was really me. I was used to different hot keys in order to modify the schematic. Only Linear Tech component models — While this is a bit annoying, it is also quite understandable since they are giving you a complex SPICE modeling program for free. There are some common passive components throughout, and you can add to libraries to add even more passives, but once you get into active parts, they are exclusively LT.

See point number 1 above in order to add models for Analog Devices, National Instruments, Maxim, etc parts. This equation can be quite complicated, especially for the models that are included for all of the LT parts. As power saving techniques become more and more important to electronics manufacturers, this feature becomes indispensable. At the very least, even if the simulation is not exact in how much power is burned during processing of a circuit, you can graph the rates of all power consumption and see which is the biggest consumer and try to optimize that part.

Efficiency calculation — Again, this will become more and more important to engineers as the focus on simple fixes in products for energy efficiency becomes more prevalent. Here you have to name the input and output signals specific nodal names, but once you do, the program will automatically calculate how much energy is being converted into useable energy and how much is being wasted.

An example would be in a circuit made to regulate 10V down to 5V. Read the original. Thanks 1 votes. I have not used, no download yet.
