R for resistor, D for diode, is much easier than clicking the picture (or even selecting from a pop up box in MultiSims case, arghh) and dragging to the right place every time. Otherwise, I would avoid it. How can a GM subtly guide characters into making campaign-specific character choices? All LTSpice does is provide a GUI and some libraries. PSPICE Schematic Note that the pulse parameters are set to be: TD = 0 (no delay, start the pulse train at t = 0) TR = TF = 1n (10-9 makes the rise and fall times almost zero) I would say that depends heavily on what you need it for.

Note that the free and open source PCB design tool, KiCad 5, now incorporates NgSpice under the hood too. This makes installing Windows programs in Linux super easy. MacSpice 2.8 which will run on MacOS 8.6 with CarbonLib 1.6 (available from www.apple.com and later systems. Here's a link with more details, it covers up more than I could in this comment: @Vlad - thanks, I actually know about the functions (I use them myself) so I should have mentioned them (will add the link now). Often the expensive spices are part of some e.g PCB design tool. Multisim, LTSpice, TINA, pSpice, are but a few of the free programs. MacSpice is an electronic circuit simulator. There are numerous free Spice packages. (Linear Technology). MacSpice simulates and analyses electronic circuits that can range in complexity from a single For example: the memory leaks that affected Spice MacSpice then builds a numerical model of the circuit and analyses this. Obviously you have found one of the drawbacks is being limited to the command line. I do like it, however. Why do jet engine igniters require huge voltages? This confuses many new users; try 'plot i(vin)'. Advantages: If you are doing power electronics this simulator is tuned for simulating switching events, as well as some other things which make it perfect for this field. schematic-capture application. Disadvantages: Unfortunately it has become so bloated in recent years that it is difficult to recommend. HSPICE LTspice ngspice PSpice I'm well aware HSPICE is an expensive proprietary simulator, but I am able to get access to it, problem is I'd have to access it on a sever via SSH.

I shifted to TINA about the time of … I guess the point is more that they are not as convenient as other simulators to use. When you need these more advanced options (not many people do or care) NGSPICE is the way to go. I'm sure some of the above is simply as I'm new to MultiSim, and no doubt I am missing something (as the above example simply must be possible in a tool like that) and no I don't work for LT :-) but it has been the only spice that I have used regularly for the last few years. SPICE can do several types of circuit analyses. I don't have experience with HSPICE, but use LTspice and NGSPICE very frequently. run may times and vary a parameter then plot results) but despite reading/wrestling for hours with it, I couldn't manage it, but a quick addition of .step V2 -15 15 1 to the sheet made it possible in LTspice.

Nevertheless, the free version allows a limited number of component, and quite slow in everyday use. PSpice vs LTspice vs HSpice. Posted by 4 years ago. PSpice available to me on my university's computers. The circuit to be analyzed is described to Spice by a set of element lines, which define the circuit topology and element values, and a set of control lines, which define the model parameters and the run controls. As a designer you should oftenly pay attention to the noise of your circuit and sadly only commercial one support well the noise consideration (Cadence, HSpice, UltraSim, ... and Xspice). I find the LTspice setup is by far the quickest out of any spice I have tried, once you get used to the key commands. The main point is that it will do all the normal stuff as good (and probably faster) than the expensive tools, but if you need the extras (e.g. In my field (power electronics), I have observed fellow engineers actively refuse to work with the company-supplied Pspice after being exposed to LTspice. In my view it can't hurt much to have around even if you do need a more powerful tool anyway. Use MathJax to format equations. Back then, I used mostly PSpice. This is a list of components and the nodes they connect to. To learn more, see our tips on writing great answers.

Cadence® PSpice technology offers more than 33,000 models covering various types of devices that are included in the PSpice software. Unfortunately, LTspice is closed source, has no scripting possibility, and you can't add (your own) code models to it. Simulation is a tool, not a magic-wand. Advantages: Well this is as close as you can get to the original SPICE. Is there a way to run MacSpice on the Terminal, similar to the Python interpreter? PSpice by Cadence Design Systems, Inc is a native analog and mixed-signal circuit simulator. I haven't tried it yet (I just use KiCad for schematic design and PCB layout so far), but hear it's worth checking out. And as you would probably like to have it on your computer, I would bet this one is out of your price range unless you have $20,000 laying around. Close. Noise analysis 5.
