PSF_utils not working on binary psf folder

Shlok Vaibhav
Shlok Vaibhav 10 months ago

I am using the psf_utils python package by Ken Kundert (https://pypi.org/project/psf-utils/) to do some signal post processing in python. I chose the format as psf and not psfxl in save options form but python still throws the following error while reading the tran.tran.tran file:

how do i ensure the psf tran.tran.tran file is being stored as ascii rather than binary format??

    The Options->Save All form in ADE only gives the option of binary formats, since it's much less efficient to use the ASCII PSF format.

    You can however force it to be used by adding "-f psfascii" on the User Command-Line Options field of Setup->Environment.

    hi andrew, 
    psf can convert the psf to ascii, can any cmd convert the psfxl to ascii? 

    Thanks.

    No. You could use the new cdspythonsrr facility mentioned in What’s New in Virtuoso IC23.1 ISR12 perhaps?
