VLSI stands for Very Large Scale Integration. Generally there are mainly 2 types of VLSI projects – 1. Projects in VLSI based System Design, 2. VLSI Design Projects. You might be confused to understand the difference between these 2 types of projects. Let me now explain to you. Projects in VLSI based system design are the projects which involve the design of various types of digital systems that can be implemented on a PLD device like a FPGA or a CPLD.
