TSMC 40 uLPeF, CLICK, power gating cells to create a ring of switches in order to ease the integration of hard macro and provide automatic control of in-rush current during wake-up.

• Make the integration easier thanks to ringstyle
• Optimization of switch placement or modification is made easier
• Simplified power grid creation
• Script for an optimized ring generation with automated insertion of the ring
• Script for automatic computation of the optimal number and size of switches required for islet construction
• Make your implementation safe
• Transition Ramp Cell (TRC) enabling automated limitation of inrush current at wake up
• TRC controls the in-rush current by design whereas traditional daisy chain method can only be verified with voltage drop analysis after SoC implementation
• Minimize your wake up time
• TRC provides both control and acknowledge signals to the power management controller for an easy programmable optimization of wake up time.
