A fresher should start VLSI in layers, not by randomly jumping into tools or UVM.
First, build a strong foundation in digital electronics — combinational logic, sequential circuits, FSMs, timing concepts. You don’t need PhD-level depth, but you should be comfortable explaining why things work.
Next, learn Verilog/SystemVerilog and write small RTL blocks like counters, FIFOs, and arbiters. Don’t just read syntax — simulate and debug your own code.
After that, choose a direction:
-
Verification → SystemVerilog, UVM basics, testbench architecture
-
RTL → timing, synthesis concepts, clean coding practices
Finally, practice explaining concepts out loud, as interviews test clarity more than memorization.
Consistency matters more than speed. Even 1–2 hours daily is enough if done correctly. Take help from blogs, AI assistant like vlsiworlds.
