How do you get into electronic design automation from Analog/Mixed Signal IC Design

When I was doing my masters I was on the fence between analog/mixed signal IC design and Machine Learning.

I chose analog/mixed signal IC Design because it seems like the natural progression from my previous job in PCB Design.

i now have 2 years of PCB Design experience and 4 years of IC Design. I have always liked math heavy and theoretical subjects and I am starting to feel like electronic design automtion would be a good fit. by electronic design automation, I mean the people who create spice simulation algorithms or place and route algorithms, or even some AI based analog design automation.

Do i need to go back to university for these?
