Power Manage Kit (PMK)
M31 offers a variety of cell libraries, including Ultra-High Density Standard Cell Library (HDSC), General Purpose Standard Cell library (GPSC), Ultra-High Speed Standard Cell library (HSSC), and Low Leakage Standard Cell library (LLSC). The PMK (Power Manage Kit) enables designers to minimize power consumption while sustaining optimal performance in M31 Standard Cell Libraries. Through a set of specially designed cells, PMK allows designers to shut down parts of a design to save power, or optimize dynamic power consumption and performance at multiple voltages operating in different function blocks.
Features
- Power-gating cells for domain shutdown
- Isolation cells to prevent unknown states that come from unpowered domains
- Data retention flip-flops
- Always-on cells powered by retention supply rail
- Level shifter cells for multiple voltage domain
