Hello everyone, I am having trouble with coming up with a spice code command to realize an non-periodic trapeziodal/square input. Someone care to help?

 

Use the piecewise linear source.

 

Using PWL, for one pulse, I'd have to have multiple arguments such that for a nonperiodic function of let's say 3 pulses, I'd need 13 arguments. Is there no other way?

 

There are ways to parameterize things to make them easier to build, but basically you are wanting to create a custom waveform, so it should not be surprising that you will have to expend some effort to do so.
