thank you for your hard work.

When inserting a PWL source file, can it be executed only with an Excel CSV file?
Please let me know if you have any recommendations instead of CSV.
note that,
I want to insert a PWL source file and observe the PWM waveform. C: \ Users \ Toshiki Takahata \ OneDrive \ Desktop \ PWLCSV.csv

When I run it with this file, I get an error saying "File cannot be opened". Why.

C: \ Cadence \ PSpiceTI \ PWLCSV.csv This file is an excel conversion of the one created by matlab. Is it because it is displayed in Japanese in the URL of the file?
