Every time I want to do something with LTspice I have to fight the UI something wicked. Doing anything relating to commands is pure torture. I eventually figured out how to do what I wanted, but it is amazing how poor not only the UI is, but the documentation. I have learned programming languages by reading the manuals. But I can't decipher the .MEAS statement in LTspice along with many other features. -- Rick C
LTspice, a great program, but that UI!

Stop reading the PDF for those game apps. Jamie

It just took a few minutes to figure out the basics of entering a schematic and running a transient analysis. It's much friendlier than some others that I've used (like EWB) and a lot cheaper too. It's easy enough to use that I also use it instead of a calculator, for simple things like voltage dividers and time constants and opamp resistor calcs. I confess that I've also used it to design LC filters by pure fiddling. Instinct and simulation can get you a long way. The HELP could be a lot better. The spotty HELP make it a lot harder to do some things. There are other resources online, but they take some digging, and many just repeat one another. One of the best kept secrets is the space bar. I suspect that part of the motivation and value of the Analog Devices purchase of LTC was LT Spice; a couple of billion dollars worth maybe. I've heard that ADI will be migrating to LT Spice for their parts. I wish the scissors icon and the run icon looked more different; I tend to click the wrong one. -- John Larkin Highland Technology, Inc lunatic fringe electronics

Or actually design ICs that have to work when sold in the millions per month range. The reality, is that of the 3,000,000 downloads, the bulk are used by students and amateurs. By that I mean this. The bulk of all electronics is IC electronics. That is, billions and billions of 10,000s of different products, sold every year are integrated circuits. The number of products with no ICs, is pretty much in the noise. This ranges from TVs, medical scanners, mobile phones, you name it, it is IC based. None of these designs (except maybe Linear Tech :-) ) are taped out using LTSpice. Its all professional tools, costing real money. Yeah, I am making a statement without actually have provable numbers, but maybe the one that does, don't post here to contradict me. -- Kevin Aylward http://www.anasoft.co.uk - SuperSpice http://www.kevinaylward.co.uk/ee/index.html

Not a chance in a billion that LTSpice has a business worth even remotely near that value. Its a freebe, so it would be simply impossible to justify it as shareholder value as anything more than dubious "goodwill". *The* fundamental reason companies buy other companies, is to take their *existing customers*, via the *products* that they *sell*. Its because the other company is eating into their markets or markets they want to enter. Its that simple. It has to be hard profit and loss quantifiable motives, that convince investors and shareholders. I propose that LTSpice played no part whatsoever in Analog Devices decision. Lets see if Mike pops up to contradict me. -- Kevin Aylward http://www.anasoft.co.uk - SuperSpice http://www.kevinaylward.co.uk/ee/index.html
