VLSI Roadmap
A beginner-friendly roadmap for VLSI engineers introducing frontend (design, Verilog, simulation) and backend (synthesis, placement, routing) concepts to build strong fundamentals in chip design and physical implementation workflows.
How to prepare for a VLSI profile from scratch?
If you are a fresher and want to start your career in VLSI and don't know where to start, follow this roadmap to understand the VLSI domain.
First, you should know the types of Semiconductors companies
VLSI is mainly divided into two parts
- •There are specific job roles in front-end design and backend design listed below.
- •All stages from logic synthesis to GDS2 are considered as backend design.
Front End Roadmap
Focuses on designing and verifying digital circuits using HDL (Hardware Description Languages).
Back End Roadmap
Focuses on physical implementation, verification, and layout of digital/analog circuits.
Fundamental topics which is essential for every VLSI profile
Theory
- •Digital Electronics
- •Analog Electronics
- •Semiconductor devices physics and technology
- •Aptitude
- •CMOS VLSI DESIGN
- •CMOS Fabrication
- •RC circuits and Network theory
VERILOG
- •Verilog/VHDL
- •SystemVerilog
- •Basic C/C++ programming
- •Scripting (Perl, TCL, Python)
Projects
- •RTL Projects
- •FPGA Implementation
- •Digital Design Projects
- •Tool-specific Projects
