Multi Voltage magic

In the last few weeks i have been quite busy with a lot of research on low power design. There are so many tutorials on Low Power and everyone's concerns/questions seems to be dancing around Multi-Voltage design. What I could sense was there were lot of designers Implementing Multi-Supply(Power-Gating) as opposed to real Multi-Voltage design. There are 3 classics style of new design style i found

1. Multi-Supply(Power Gating)
2. Static Multi-Voltage
3. Dynamic Voltage and Frequency Scaling

Lets us discuss about Multi-Voltage design in the forthcoming posts. Like any other design implementation, MV design has its own challenges and much more difficult to sign-off.

I would like to classify the different stages of the design into small segments so that we can discuss one by one.

• Design Infrastructure
• Architectural level consideration
• Microarchitecture
• RTL Design
• RTL functional verification
• Implementation
• Functional Sign-Off
• Silicon Signoff
• Resources For Help

Next post is going to be a in-depth technical article i guess!
