Import several pwl signals through one file

Hello everyone,

I'm trying to import 300 pwl signals as input of my circuit and run the simulation. I already know how to import single pwl signal as input (use vsource and select pwl file), but is it possible that I put 300 pwl signals in one csv file and import it, and after simulation, I can get 300 simulation results? I see someone has already asked about this two years ago https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/43338/how-we-can-use-the-single-vcvs-file-containing-n-waveforms-for-generating-the-n-voltage-waveform-sources-in-ade-x  Does is possible without writing Verilog A node now? I'm using IC6.1.8.

Another question is, what does "pwl file as design var" means?

Thanks a lot for help!

Regards,

Holz
