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! ...

Hello I am using the PSPice Orcad I have many drivers with the same voltage. Is there a way to do the simulation with only that voltage and use reference point to that voltage instead of using multiple line from the source to each driver. This would reduce a lot the amount of lines and would make things much clearer. THANKS, k

I have a schematic that I would like to run a simulation of. I'm using a spice program for the very first time today. I've got the schematic drawn and I'm trying to figure out how to start a simulation. I'm using OrCAD PSpice demo version because that's what my school tells its students to use. I'm aware of LTSpice but I wanted to use what the rest of the students are using. I'm not l...

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 ...
