Hello
I would like to have a non linear voltage source, so I have used a VPWL source.
I have define about 16 point/times to be very precisely, but it seem that at 10 points the simulation don't take the others value of my source.
At the 11th point we have a saturation with the value of the last point.
So how can I modeled the source I want with more than 10 variables?
Thank you
Cordialy

Hi,
There are many options to add VPWL sources in your desgin. I suppose, you are placing the component VPWL form the library source (if not, let me know). It is possible to use other options that could be even quicker and easier. Maybe you could try with these ones:
1. Click on Place --> PSpice Component --> Modeling Application --< Sources --> PWL Sources and then add a PWL File (text file) or PWL Point (you can add additional points if you need more of them.
2. You could use the component VPWL_FILE, where the points are taken from a text file.
Let me know if you continue experimenting such phehomenon.

Roberto
Hi
Thank you a lot for your answer, it was really usefull.

Following to the guidance of uno online, you can use a piecewise linear voltage source (VPWL) to create an arbitrary waveform as a set of voltages at various points in time. The VPWL source allows you to describe a transient voltage waveform by connecting time-voltage pairs, which you define. You can describe the waveform data as a set of points that you enter directly into the Time/Value Pairs list, on the Parameters tab of the Sim Model dialog. There is no upper limit on the number of points you can define for the waveform.
Useful information. I had trouble with it too. I can now repair geometry dash online once again. My problem was solved with the aid of both replies!
The information you share is extremely useful, I can learn from you and solve my work better. The fnaf security breach game is a survival game that will challenge players through terrifying nights at Freddy's Pizzeria and other areas. It becomes more addictive, join in and experience.
