Always-on tie cells for low power designs and method of manufacture thereof

Abstract:

Always-on (AO) tie cells, whose power supply has to remain on when the primary supply to the power domain is off, are used to implement logic constants. In accordance with embodiments of the present disclosure, insulated and non-insulated AO tie cells improve the QoR of the layout design and lower the power consumption.
