Not sure what you mean. Can you draw and upload a sketch of this waveform? You should be able to do this with a PWL source. Please see: [https://docs\.google\.com/document/u/1/d/1OWZVVFRAe\_2NW3WratpkA\_SGuHa5AcRow5ZRfvcoVTU/pub\#h\.2grqrue](https://docs.google.com/document/u/1/d/1OWZVVFRAe_2NW3WratpkA_SGuHa5AcRow5ZRfvcoVTU/pub#h.2grqrue) in (3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) Here's what I think you are trying to create: [https://easyeda.com/editor#mode=sim,id=062fdd9407aa48718ffd6cc717b6f210](https://easyeda.com/editor#mode=sim,id=062fdd9407aa48718ffd6cc717b6f210)

Hi, Thanks for the answer, I couldn't do it with PWL becuase it is limited to 5 values(of times and voltages), mabye i'm missing something? This is what I want to achive:  I couldn't open the last link(permission denied).

Oh, sorry! My bad. It's Public now. If you edit the pwl statement directly in the schematic, you can have as many Time, Voltage pairs as you like.
