The two dominate EDA companies are Cadence and Synopsys. All of the digital design tools for synthesis, place and route, and static timing analysis use the Tcl language as the built in scripting language. These tools have literally thousands of built in commands.
You can look up some of the tools like Cadence Innovus that I use every day. A single license has a list price of over $1 million. We get big discounts because we have about 800 licenses.

Then you write more Tcl code to script things within the tool. A standard thing is building a power grid. You need to write a for loop to build a metal 1 stripe every 5 microns. That's done in Tcl.
You have a list of clocks you need to define with names and frequencies. Use a Tcl array and a for loop.
Our CAD flow is literally tens of thousands of lines of Tcl code to take Verilog and go through all the steps until we get a GDS file with mask data to manufacture.
The confusion here stems from an acronym collision between Exploratory Data Analysis (where R and related packages like ggplot are popular) and Electronic Design Automation.
LOL, I just thought the person I responded to was confused.
There are so many TLA (Three Letter Acronyms) that are the same across industries with completely different meanings. I was on the ECE subreddit which is for Electrical and Computer Engineering. Someone posted a rant about how annoying these children were, how the pay was bad, and the parents were awful. There were some funny comments about how some engineers acted like children and others about the new grads. Finally someone pointed out that ECE was also Early Childhood Education and pointed them to a different subreddit.
