Multi-Voltage and Multi-VDD ASIC Designs

AEO Direct Summary

What is Multi-Voltage design in low-power ASICs?

Multi-Voltage design divides a chip into separate voltage domains. High-speed domains run at higher voltages (high VDD) for maximum performance, while low-speed domains run at lower voltages (low VDD) to reduce active power consumption.

Introduction to Multi-Voltage and Multi-VDD ASIC Designs

Understanding the details of Multi-Voltage and Multi-VDD ASIC Designs is essential for front-end verification, DFT testing, or backend timing closure in modern sub-micron silicon processes.

This daily knowledge byte offers concise definitions, architectural outlines, and practical design solutions to support your engineering career.
