Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistorsinto a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip.

This cours explores the HDL and CMOS based design techniques, testability in logic circuit design, SoC issues and PLD architecture along with many interesting concepts in VLSI design.
