Hello all! I try to build a power supply. Therefore I would like to simulate my circuit with the student version of Pspice. I find some models of voltage regulaters on the internet. Now I ask, if it possible to use these models with the limited version of PSpice. Has anyone of you put the model into the normal liberary? If yes, how can I do it? I would be happy about a fast response! ...

I offer to share with you a TUTORIAL but don't know how to get it into your hands. The TUTORIAL is about 15kB, zipped, and describes the step-by-step process of using FREE femm 4.2 to analyze a simple PCB structure to calculate values to then use in circuit simulation, LTspice/PSpice. The sequence can be modified for use in analyzing really complex structures, structures where th...

Hello, I just finished creating a circuit, it's a drum machine, but I've done the whole thing on a solderless breadboard. I was wondering if anybody could give me any tips on how I could go about transferring my design onto a PCB. If anyone could reccomend any software or such that is good for this? I have a copy of PSPICE, but I'm not sure if that's mainly for simulations. I've seen the ...

A question presented on the LTspice list by John Woodgate prompted my answer, which may be of interest to other LTspice/PSpice/whatever users: Here's an extreme example of multi-parameter stepping... In this example "Case" was stepped 1, 2, 3, 4 to get all the combinations needed by the test (IBIS model generation :-

For sometime now I have been trying to build a behavioral model of logic gates that was consistent with real-world behavior when mixed into an Analog environment. (Existing logic models, such as those in PSpice and LTspice are state machines and do not behave properly when used for Analog applications, such as when you build a crystal oscillator around a 74HCU04.) So I now invite you to ...

I am new to PSpice and OrCAD. I have a school project that requires making a circuit board. I don't need to simulate it. I'm looking for the fastest approach to getting the PCB made, and that's all. My school has Orcad, so that's what I'm using. I opened up OrCad Capture. I have a choice to open a new "design" or a new "project." Click on File/New Design and it opens up a schematic....

hi, I have two 12v batteries which I am hooking up in parallel using a mechanical switch (via the ground). I am attempting to swap the mechanical switch for a mosfet so I can control them from a distance. I tried to model in pspice but this is harder then I imagine. I tried it experimentally, but when I hook up a iRFz44 , the batteries stays in parallel no matter the voltage in the base. ...
