Assistance running IEC61000-4-2 simulation

Hi there

I’m very new to SPICE modelling, but understand enough to get by. However, this has me stumped.

I’m trying to replicate this tutorial, but I’m not able to get any ESD pulse at all. This is from the user generated SPICE model, not the ideal curve from the Matlab txt file mentioned in the article.

Could somebody more experienced please take a look at my files and see where I have gone wrong? (I cannot upload my .asy file)

Thanks in advance, Dean
