What is VLSI Design?

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. 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.

Very large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions of MOS transistors onto a single chip.-Wikipedia
