Is there a reason why 午 and 年 look so similar? I've used multisim back when it was called Electronics Workbench. I have only used PSpice. Here are examples of how I use both packages. Users will, however, need to supplement these with following reference and training and information: Intel is a registered trademark of Intel Corporation. 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. Distortion analysis 7. Brownout. You can't really beat that. 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. For example: the memory leaks that affected Spice To learn more, see our tips on writing great answers. (Linear Technology). To subscribe to this RSS feed, copy and paste this URL into your RSS reader. In my field (power electronics), I have observed fellow engineers actively refuse to work with the company-supplied Pspice after being exposed to LTspice. of International Business Machines Corporation. Advantages: Well this is as close as you can get to the original SPICE. 2. It does not have What is the current school of thought concerning accuracy of numeric conversions of measurements? Additionally, it has (IMO) an intuitive interface and doesn't try to hide the netlist from you. As an addition to the previous answers, LTspice is a great freeware with limited possibilities on the digital parts: ibis models are not considered at the exception if you own/develop/find a software.

Unfortunately, LTspice is closed source, has no scripting possibility, and you can't add (your own) code models to it. There are numerous free Spice packages. In my view it can't hurt much to have around even if you do need a more powerful tool anyway. My short answer is to just go with LTSpice, it is one of the best simulators on the market and it is free. Like Reply. However I have no actual experience using it. The design of any circuit board requires very specific software. Decoupling Capacitor Loop Length vs Loop Area. 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). Browse Cadence PSpice Model Library . The quality of the results depends on the accuracy of the netlist Is TINA-TI as good as PSpice for simulating RF? Welcome to PSpice Forum.

Joined Jan 10, 2012 2,390. 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. Multisim, LTSpice, TINA, pSpice, are but a few of the free programs. Users may prepare netlists with a MacSpice then builds a numerical model of the circuit and analyses this. Abode plot is generated. 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. New comments cannot be posted and votes cannot be cast. I shifted to TINA about the time of … 3. It is usually cheaper and quicker to simulate a design than to build a prototype. 12 comments. Cadence® PSpice technology offers more than 33,000 models covering various types of devices that are included in the PSpice software. Archived. I would say that depends heavily on what you need it for. Translation of PSpice Netlists. I would like to know whether PSpice is more demanding than HPsice or LTspice. I just tried to run a transfer function analysis in MultiSim in this manner (i.e. usually cheaper and quicker to simulate a design than to build a prototype. Welcome to PSpice Forum. Use MathJax to format equations. I'm just trying out MultiSIm from NI (expensive orcad type tool), and it has lots of pretty virtual instruments (e.g scope, distortion analyser, etc) and monte carlo analysis (which LTspice does not have a "convenient" version of - it does have some functions you can use though as Vlad points out, here is a link on using them) but to be honest I find that 99% of things I could do on LTspice. monte carle, PCB level anaysis based on actual routing/IBIS models - Altium does this excellently) and all wrapped up in one design tool then you may need more than if can offer. XSpice is ngspice like with multi threaded and shared processes possibilities to speed up simulations. circuits, and to reduce simulation time; MacSpice provides a robust multi-parameter optimizer users who range in experience from novices to retired integrated circuit designers. One may include a scripting block in the netlist which is quite powerful. HSPICE is not available for Mac but there are a few alternatives that runs on macOS with similar functionality. PSpice is a complete simulator that allows you to analyze the behavior of an electric circuit board. The parameter steps are hard to distinguish from different voltages. It is used at various universities internationally for research and teaching. NGSPICE can be used with gnuplot for very nice, programmable, graphical output. The high quality of the MacSpice command interpreter The UI kind of passes me off, but it is a very useful program. My comment was supposed to add up to your response, but sometimes I can be quite spartan, I still don't know whether I should feel prowd or not :). The most popular Mac alternative is Ngspice, which is both free and Open Source.If that doesn't suit you, our users have ranked 5 alternatives to HSPICE and three of them are available for Mac so hopefully you can find a suitable replacement. the .param, .step and .measure commands for doing things like running an analysis many times and varying parameters. What is the highest road in the world that is accessible by conventional vehicles? I love the fact you can watch a virtual scope and turn pot's to see real responses. Nevertheless, the free version allows a limited number of component, and quite slow in everyday use. Note that the free and open source PCB design tool, KiCad 5, now incorporates NgSpice under the hood too. but incorporates many improvements to Spice 3f5 – from simple bug-fixes to entirely new It is 3) To compare pspice and ngspice for accuracy, to make sure that I get Install playonlinux in Ubuntu with.

This thread is archived. It has LTspice does have Monte-Carlo and Worst-case analysis, but, true, it's not something that can be readily found. I refuse to install it on my own computer, because it messes with the registry a bit too much. Ngspice is not limited to the command line. report. PowerPC is a trademark This confuses many new users; try 'plot i(vin)'. 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. LTspice is much user friendly than PSPICE, but that is just my point of view. PSpice A/D Manual and Examples, Part 2 In this example we will simulate an inverting operational amplifier using one of the most common commercial operational amplifiers, the µA741. 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. Then you can also use TINA from Texas Instrument which is free and allows as LTspice a bit of extra digital and ibis model. This software for Mac OS X is a product of Digital Thought Software. I used SIMetrix when I was making an amp for sound system that required a noise floor of >100dB. Sadly, PSpice for Mac is not yet available. MacSpice User's Guide 2 CIRCUIT DESCRIPTION 2.1 GENERAL STRUCTURE AND CONVENTIONS. MacSpice is an electronic circuit simulator.

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) schematic entry but there are solutions for that (e.g. Overall: If you REQUIRE reliable results (Military or high end industrial) then HSPICE is the way to go. I've recently realized that I can't do everything easily in ngspice, mainly because analysis has to be performed through the interpreter. Back then, I used mostly PSpice. 4. I haven't been made aware of any, it isn't considered quite as accurate as HSPICE, but it isn't inaccurate by any means. Plus, it is FREE. Making statements based on opinion; back them up with references or personal experience. LT Spice is almost always well spoken of, and the price is right.
