Did you Know?
There is a lot of confusion about multi-voltage in the industry. An island is a block of logic which can be controlled up-to 7 ways with different electrical controls, as shown. (More are possible as AUX indicates).
Any variation in an islands electrical connections across the die/system and any variation in time on the power supplies connected to these islands is multi-voltage design.
Multi-voltage design comes in many flavors, all of which can be expressed using this island concept :
2) Dynamic Voltage (and Frequency) scaling
3) Standby/Sleep States
4) Power Gating
5) Retention/Balloon latches
6) Body Bias
There are many such low power fundamentals, which will be covered as a part of "*5-day Low Power Design Workshop using Sky130*" happening between 14th-18th July, and industry is widely open for candidates with low power profile.
