Linux and Scripting

Linux

Linux and Scripting are not only meant for IT administrators. Almost all EDA tools in the Semiconductor industry are made for the Linux environment and are controlled through the command line. Hence, getting familiar with the Linux environment is a bonus skill, placing you a step forward than others. There is no need to replace your windows OS with a Linux-based OS on your system, to play with it. You can use a virtual box to run Linux without affecting your normal Windows OS.

Though you can find many videos on how to run a Linux environment using VirtualBox, here is a video by a channel named “It’s FOSS – Linux Blog” – Click here

Once you have access to the Linux environment, you have plenty of resources that teach you Linux from the basics. There are Udemy courses, NPTEL courses, blog pages, dedicated websites and the official Linux Foundation website as well.

Scripting

As mentioned above, EDA tools are operated using command line (most of the tools are developed for Linux environment and are extensively automated via TCL, Perl, Python scripts). We use a bunch of commands to perform a task. But typing commands every time is tedious as well as time-taking process. Hence, we dump all those commands in a script and run the script which is nothing but running commands one after the other based on some conditions (Though this is a vague understanding of scripting, in simple words, this is what it means).

There are many languages like TCL, Perl and Python, which we use to write scripts. There is also a concept of Shell scripting. You can find their official websites to learn about them.

Here are few resources which can help you.
