I have been using orcad pspice demo version 9.1 for several years. Since today, when I try to open a .CIR file it says: "failed to connect to the pspice simulation server" I can't even view it. This is before I try to simulate. I limit myself to .CIR files that I have already simulated. Am I the only one? Does a demo software really need to connect to a server? Then did this server ...

Hi all! I need simulation file for this IC. If someone has it, please share with me. I found here some files for UC3843, UC3842, but they are current mode, and I want something with voltage mode for flyback converter, which has voltage regulated from 30V to 300V. So I will be gratefull for model UC3825 or information how to simulate in Pspice PWM modulator with Soft Start and limit max cur...

Hi Folks, Reached an end of a rope here: How do you make a worst case simulation in PSpice (or even Monte Carlo for that matter) properly find the extremes for an opamp offset voltage and input bias current?

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...


PSpice Gain/phase model for S/H and quantization in software loop (digital SMPS)

Hi I have implemented a digital SMPS in a Cortex M3 controller. The feedback of the SMPS is done using the TL431 and opto coupler feedback. The feedback is sampled by the ADC at 10kSa and the sampled values controls the duty-cycle of the SMPS. It is stable, but I would like to simulate the loop in PSPice. The ADC has sample and hold along with quantiziation that affects the gain/phase. Th...

Hello Folks, On my PC this software crashes often and hard and needs too many re-installs. It slows down one project to a crawl here and that needs to get done. I could use older versions as long as my client can read the files into 16.3. Question: In your experience, what was a relatively stable (as in "not many crashes") version I could try to go back to? The license should allow a do...

When you interview job candidates, you pose standard problems, of circuits, PSpice, maybe Mathcad, etc. Textbook stuff, you expect he knows, reviewing his resume. Microsoft and Google are famous for posing brain twisters, stuff "outside the book" (if any exists, nowadays with the net). Do you do this? The obvious idea is to test for originality. How much weight do you place on the ...

The thread related to large signal PSpice models and an emitter follower comes from the following problem: I have an oscillator that should drive a digital part of the system. In short, what is the best way to achieve this? My first attempt has been a common base Colpitts oscillator that gives a signal riding on the +Vcc rail. This has been AC coupled to a 74AC gate biased to the poin...

PING: Aylward or other Spice Expert... Bringing up a 0.18u/0.35u Vanguard process, building up the PSpice model libraries. Discovered strangeness: ALL devices have HDIF=0.2u, except "native" NMOS, which has HDIF=0.02u!! I thought this might simply be a typo, but that HDIF value is repeated in each of the corner parameter statements. 0.02u seems awfully small to me. Can this be...
