Best Circuit simulation Software?

[Siike92]

I recently downloaded LTSpice IV to use for testing circuits. Before I start to really learn the software I'd like to know if it's what I should be using or if there's something better. Basically I'm just testing simple circuits, but I do need the software to have a virtual oscilloscope.

Well, I can't speak for others, but I learned LTSpice. It works good. You get waveform like on the oscilloscope. For normal frequency stuff, I get everything I want from LTSpice.

I agree.

This program is easy to use, fast, accurate and free.

And, it is fun to use.

I visit the yahoo LTSpice Group and the experts there get amazing results by direct programming.

I just use it to confirm (or deny) results I get with a calculator or sometimes to teach me how a circuit will work.
Sometimes I use it just because it is fun to use.

Here is an example where I varied the gain of a transistor by use of a direct command:

Thanks for the advice. I figured LTSpice was the standard. I just wanted to be sure I wasn't missing out on anything before I started learning it.

Learn it, it's easy. Two or three posts from vk6kro helping me, I was on my merry way already. Any question, just post here.

Hi,
I need a simple square waveform generator circuit that uses opamps

Probably should have started a new thread for that question, but here is a opamp square wave generating circuit. It works well as long as you have an opamp with a decent slew rate (depending on how high of a frequency that you want to generate).

Thanks a lot
