Screenshots simulation images: Included in PSpice is a limited library of Coilcraft RF inductor models. Mainly it's: Models for extreme corner cases (e.g. Obvioulsy I can use a calculator but then what is the purpose of the tool? As MOSFET Gate acts like a capacitor, steady state gate current is zero, we can take the values of R2 and R1 several kilo Ohms, or hundreds of kilo Ohms. That reminds me of something I overheard one time. Although initially designed as a simulator for electronic circuits, it has now become an essential tool for board design that transmits electrical signals and requires analog elements utilizing high-speed CPU operation. pspice vs hspice All spice type programs are a direct copy of the spice program developed and maintained by the University of California at Berkeley USA. The VAMPL is set to 9. The SPICE projects are classified according to the different circuit categories. A Spice model file is nothing more than a text file with a different extension. These can be subsequently restore from same UI. TINA-TI vs LTSpice (vs others ?) LTspice can, however, run PSpice semiconductor and behavioral models and is generally a much higher performance simulator, so you might move your PSpice simulations to LTspice. This a library for LTspice, Fortunately, the two syntaxes, with few exceptions, are compatible.To model a NMOS long channel, with 1 um minimum drawn channel length, copy the first .model statement and paste in the editor window, save . The GLaplace element is used in PSPICE to describe a frequency-dependent impedance. Here I am again using my beloved Python and doing maths stuff.

Modelling a DC motor using LTspice, Simulink and Matlab Electrically speaking, a permanent magnet DC motor can be modelled as follows: applying LKT we obtain the following differential equation Check “SPICE Projects” and the category circuits you are interested in, You can refine your search using the filters “SPICE software”, “complexity” and Free or For Credits projects. In general the differences are minor. LTspice is (for me) much more straightforward to use. em.) (all combinations) What if capacitors are +/-10%. Pspice and Hspice are commercial products that cost money (unless you torrent them); Ltspice is freeware. The -180 degree Vo/Vi phase of the inverter should be lost above the cutoff frequency and become +90 degrees because of the 1MEG + Coss feedthrough from input to output. Would this be a problem with the model or my ability to use it? Pspice and Hspice are commercial products that cost money (unless you torrent them); Ltspice is freeware. If LTspice is already open, close and then reopen it. vs. PSpice This white paper investigates the Quite Universal Circuit Simulator (QUCS). Figure 3. 4 Using Texas Instruments Spice Models in PSpice A quick examination shows that it is essentially a .cir file—a legacy from PSpice’s past. The exceptions are the encrypted files provided by some publishers. If you want to use the heater model, a symbol will need to be made up for it - this is easy with LTSpice.

LTspice/SwitcherCAD III is a complete and fully functional SPICE program (electronic circuit simulator) that is available free of charge from the Linear Technology Corporation (LTC). Of course, LTSpice is quite capable, too. P. PickyBiker Member. In this article, we will use the following schematic as an example to explain the Waveform Viewer. Spice is a somewhat complex but very powerful simulation tool. This motivates me to try TINA-TI. (resistors are +/-5%) So what happens when some resistors are 5% high and some 5% low. Hello, I have done some simulation in LTSpice, for LTC4364-2, and due to good results I would like to introduce this circuit in an Orcad PSpice simulation. But it's quite unfortunate that LTspice Linux version is not available, it's built to run on Windows and macOS only. Each program has it's quirks. I get the impression that PSpice & LTSpice just add a whole new layer of problems and misdirection to designing circuits. For instance, in Example PS4.1, we will use the commercially available D1N418 pn-junction diode whose SPICE model parameters are available in PSpice. Click images to enlarge. LTspice is the only SPICE-simulator which is free of charge without any limitation and with a built-in GUI for schematic and waveforms. It looks like your NGSPICE result is numerically correct, but it is difficult to see how it can come out of that schematic. Note the use of the VSIN source for this input. Open a … In this case, we want to plot the V(out) vs. simulation run index. You can try LTSpice out for free. Suppose its output is the voltage we want: V. Now the input to the ideal integrator is evidently dV/dt. If we wanted, we could put both probes on simultaneously and then both traces would show up in the same plot. Anyway, PSPICE has its own (incompatible) digital primitives, LTSpice has another, Altium uses SimCode, Multisim uses some other kind of code, etc. Below is a comparison, Fig. For a better experience, please enable JavaScript in your browser before proceeding. but free version of pspice is good too.
