file. If you choose this option, the circuit will depend on the text file. When this button is
selected the following become active:
•
Filename — click on the button to the right of this field and navigate to the data file.
The data file must have a .txt extension to be used.
Note If you do not specify a filename, the output of the PWL current source behaves like an
open circuit. An error message does not display in this case.
•
Edit file — click to open the data file for editing.
•The
Enter data points in table radio button, used if you wish to manually enter the data
pairs, without referencing an external file. If you choose this option, the following become
active:
•
Time and Current columns — where you enter the desired time and current data points.
•
Initialize from file — click to view the data pairs from a specific file. If you choose this
option, the circuit will not depend on the text file. The data points will be loaded and
saved into the circuit file.
•
Repeat data during simulation — enable to continuously run the file during simulation. If
this checkbox is not enabled, output from the source will cease once the final data pair has
been read.
