have VCVS value by equation expression,this output has to perform like resistance element value,how to implement using pspice(abm)
To design a motor model, you basically have to consider how the mechanical quantities (rotational speed, torque, inertia) are related to the electrical ones (current, voltage). You should be able to get the fundamental equations from literature if you can't find them from the scratch. Also the load has to be considered of course. You can implem
Hi all, I want to implement the clock sync fuctionality for one of the devices in pspice.The local oscillator produces oscillations of max 2MHz.The frequency comparator block has to compare the signal from local oscillator with the frequency of signal applied across one more pin.Based on which frequency is higher the local oscillator must tune
Hi! I need some information on how to solve convergence problems (time step too small) when I'm simulating power electronics systems which include analog parts, D latches and abm parts. Also I have large currents and voltages to simulate at 70 kHz. I already read material from orcad's site, changed some settings in simulator and still have problem
Hi! When I simulate power electronic circuits in pspice I got large *.dat file as a result (<=2GB). Circuit is very big with abm, digital and analog parts and with large values of voltage, current and requency. Is there any way how can I change deafult max value for this in pspice which is 2GB (I need bigger) or how can I change some (...)
i want to analyze the noise performance of my circuit,but i can't find any noise sources in pspice and i need pink noise and white noise source~~ so ,how to make it in pspice? thanks
Hi, I m doing work on Single-phase Unipolar Inverter , I have made all the schematics in Orcad Capture and want to simulate it on pspice but problem is that how can i generate the PWM signal in pspice.
How do I create a analogue behavioural model of a comparitor with hysterisis in pspice. I need upper and lower thresholds of 1.25 and 3V. Thks
Hello all, İ want to plot my bandpass filter's transfer fucntion which is in s-domain.For example i have Vo/Vi=(0.03s/s^2+3s+5) how can i plot it in orcad pspice(v16.3)?
2nd Tutorial on pspice
Hi I am a beginer in pspice. I would like to know if its possible to define user defined functions to be used along with power electronic circuits(as in case of matlab) . Any references would be helpful. Also i wanted to know if its possible to implement a solar panel in pspice(either as a lookup table of I-V characteristics or physical model)
It is still showing transconductance of 1S Looks like. But it's surely not a general pspice problem. You may want to inspect the generated netlist. Or post the project files.
Hi, I've been working on a power device macromodel based on abm, but I got stuck in convergence issues (transient analysis) when Vdd goes over 100V I changed RELTOL, ABSTOL, VNTOL, etc., but I wasn't yet able to have it working with higher voltages. The model is in the attached pdf. I am using pspice from Cadence SPB v16.3 Any ideas? T
When trying to simulate this circuit, I get this error. Apparently it's before the netlist is created, because when I try to view netlist it doesn't do anything. Anyone know why I'm getting this error? Creating pspice Netlist Writing pspice Flat Netlist C:\ ERROR Design is not annotated. This is an abm t

You must study the syntax of SPICE and pspice.You need change the model manually from one format to anather format. You need deep knowledge of spice model. Good luck!
Hi , If u have installed pspice then in their opto library they have the model for led MLED96 which should serve ur purpose. Vicky

i would like to simulate my entire circuit containg 74 series ic and 2 fpga . i would like to see the pspice simulation of the entire circuit alongwith the fpga code. i know it can be done in multisim and i have done it for small vhdl codes. it is no good for large program. can it be done in orcad 9.2 or PSD 14.2? what are the other tools which
Hi, U can find photo diode model in the opto library of pspice Vicky
Hi, In my job we are planning to buy a electronic simulation program. I know there are to well-know programs: pspice and Multisim2000. It is hard for us to choice. Some guys want Multisim2000, other prefer pspice. Would pspice and Multisim2000 user please share your valuable opinions with me why should I choice (...)

I use pspice as schematic editor. I am not able to generate pcb netlist. pls help me Thx George.
Hi all, Any user experience on Analog Designer ? How does it compared with pspice ? Thanks.
Hello guys, I'm now going on an amplifier project, I can simulate the ferquency responds, offset, overshort, and so on but distortion in a dos version pspice (5.0). Can anyboday tell me how to simulate distortion in this version of pspice? Is there any better choice for distortion simulation? Thanks in advance.
why said T-spice is low end tool ??? pspice is board (system level ) simulator but Tspice already support level49 model , I think it can run on real ASIC design .. by the way , who can compare this tool on PC platform  Smart_spice tanner Tspice Dolphin smash Mycad mySPice which is more accuracy tool o

I have one question about pspice , when I do a simulation of a low pass with switched capacitor ,I have a bad Fourier analysis , the response of a pulse has a bad Amplitude pspice doing a DFT but I cannot fix the sampling period. So if someone has a idea?
I need the pspice model for simulation. Any one tell me, where can I gei it?
Hi I'm looking for a version of pspice that works on Windows XP. I've tried version 8.0 but it doesn't work. Can anybody tell me which version must I use and where can I download an evaluation version of it? Thanks Hi, I am using psd14.1 release and pspice is working very well in winxp. All the latest versions of pspice
Has anyone an idea when the guru's from OrCad will finally write a spice engine that supports multi processors, Hypertrading. I have setup a server where I use a double Xeon Hypertrading processor (read: 4 processors) and when performing a simulation with pspice, only 25% of my CPU is used :? Topsimulations (ASIC) will take quite a long time :D
hello all, i am using orcad pspice v10.0 and am trying to model a non-linear transformer using the Advanced Analysis tools. i see there are many different cores to choose from, but i do not understand how they relate to core datasheets? for example, from the advanced anlaysis CORE library, i find this core: ETD29_3C85 i see it is of s
Hello, I am trying to simulate a flyback switch mode power supply. i have ONLY the PWM controller chip UC1844A and associated circuitry. i try to first see this device switching, 50% duty cycle. then, when that works, i move on to model rest of circuit. but i can not get UC1844A to simulate at all without causing Convergence errors!! ha
Hello friends, I have a question connected with a problem. I would like to simulate a temperature-dependent resistance. But i want not to simulate it over a temperatur range. I want to simulate it with a fixed temperature (for ex. at 27°C) As soon as current flows through the resistance it changes its resistance value, by becoming smaller.

how to generate pspice files from windows softwares? is there any softwares can do the circuit capture, then export the netlist as pspice?
Can any one tell haw does pspice evaluetes the beta of the bipolar transistor versus the suply current.
Hi, If you are using pspice Schematic Capture (not Orcad Capture), in the menu Analysis, select Probe Setup and check Restore last Probe session.
I don't know much about pspice (but quite enough of spice), but first question is: are you using a special capacitor model or just an ideal capacitor? What about if you left blank where you put CAP as model? In crude spice what you want to do would be .param valuecap=1p C2 x y ac_sweep_type np fstart fstop SWEEP valuecap
Hi You have probably choosen a "VSTIM" generator in the "Source" library of pspice. That's why you need to enter a value for the parameter "stimulus" of this "VSTIM". If you only want do proceed an AC response of your circuit, you can choose a "VAC" generator instead a "VSTIM". In this case, there is no "stimulus" parameter, but you need to p

Hi, I need to measure and plot time jitter (or phase difference between two clocks) using pspice. Does anyone know how to do this? It has to be done with pspice and in time domain.
Can orcad pspice generate s2p file? and ads can be used combine with pspice? thanks!
Xspice is based on the original Berkely spice (it can do everything the original spice can) but includes the ability to incorporte arbitrary user models. I think it originated at Georgia Tech so you can probably find more info there. A lot of the newer EDA spice packages are based on xspice. pspice also has extensions to the original Berkely s
