PIECEWISE LINEAR VOLTAGE Source BUG

[ZG]

I want to use PWL source to analyze the signals from my digital oscilloscope.

File MEANDR.txt contains 5000 points of voltage(mV) in time domain(s).

1) If I will use this file by "Use data directly from file" option there will not be any signals at the output of the source.

2) If I will use option "enter data points in table--->Initialize from file" and push the button "Run Simulation" Multisim breaks down.... ......... but it starts to work correctly if I will reduce original file from 5000 points to 2000-300 points. (File MEANDR_MODIFIED.txt)

Can you fix this bugs?

Thanks!

Hi  ZG,

Your data is going to give Multisim a problem because of the format, Multisim expects two columns time and voltage.  On the Time column your data goes from 1 to 5000 so Multisim is going to have to simulate for over an hour and in simulation world this is an eternity.  I modified the data so that Multisim only simulates up to 5 sec.  Your voltage column is supposed to be in mV so on each line you need to place a mili at the end otherwise Multisim is going to output KV. Using Excel and Word I modified your data to something that Multisim can understand and the file is attached.

Thank you! It works well with "Use data directly from file" option but only if there are no cyrillic symbols in file path.

(But Multisim  breaks down the same if "enter data points in table--->Initialize from file)
