Create non-periodic signals with vpwlf

Sometimes, some special input patterns are needed to test your circuit, and this tutorial will tell you how to create your non-periodic signal using vpwlf.

Firstly, create your waveform file, and the following figure shows a simple waveform file.

The first column is the time whose unit is second, and the second column is the voltage. In order to give the waveform, you need to decribe the voltage value at each point where you waveform will change.

Then create your library, and cell view as usual.

Add vpwlf by going to -> ncsu_analog_parts->voltage_source->vpwlf

Input the directory where you save your waveform file in the field of PWL file name:

For example, here I input: /nethome/users/hgrfd/test/b.pwl

The following schematic is used to test what type waveform will be generated by this pwl file.
