The Art of Verification
Hi, I’m Hardik, and welcome to The Art of Verification.
I’m a Verification Engineer who loves to crack complex designs and here to help others commit to mastering Verification Skills through self-learning, System Verilog, UVM, and most important to develop that thought process that every verification engineer should have.
I’ve made it my mission to give back and serve others beyond myself.
I will NEVER settle for less than I can be, do, give, or create.
