vpwlf error:Syntax error in waveform file `/home/users/pratike/data_interp_msb2.xlsx' at line 23

pratike

Hi,

   I'm trying to load .xlsx file using vpwlf. My file contains strictly increasing data,

still it gives error as : "Syntax error in waveform file `/home/users/pratike/data_interp_msb2.xlsx' at line 23".

  I'm using Virtuoso version IC6.1.7-64b.500.11

Below is portion of my data in file:

(My data contain only column 2nd and 3rd, 1st column (line no) is for your information to check line no)

1 0.0000000000 0

    You didn't mention which simulator you're using (or the version of the simulator, which is more important in this case than the Virtuoso version), but I'm guessing it's Spectre - looks like a Spectre error message.

    Assuming that the file is not just a text file with the suffix ".xlsx" but a Microsoft Excel spreadsheet, then that's not supported. I don't know why you think that you can use a spreadsheet with spectre's PWL source. It's not documented anywhere that you can do this - instead the source expects a text file with two columns of numbers (white space or comma separated). I tried with the content you provided above, and that works. With it in an Excel spreadsheet, I get a similar error to you (a different line number) - hardly surprising that it gives an error since the spreadsheet is a binary file.

    Regards,

    Andrew.

    Actually I wanted my time data to be accurate upto 10 decimal places, tried it with .csv file, but it did not take any formatted data. That's why I go for spreadsheet. I didn't thought of .txt file.

    Now, I used .txt file and it works.

    Thank you so much Andrew for your help !
