SoC Power Management Design and Verification

SoC Power Management Design and Verification

Power is a primary design criterion for bulk of the semiconductor designs now and a key reason behind the shift towards multi-core designs as increase in power consumption limits increases in clock speed at the rate we have seen in the past. Voltage and Clock are two of the strongest handles for managing chip power consumption. We look into the details of some of the key power management techniques that leverage voltage and clock as a handle and their impact on chip verification; these include Multiple Clock Domains, Clock Gating, Power Gating, Power Gating with Retention, Multiple Supply Voltages, Dynamic Voltage Scaling, Adaptive Voltage Scaling, Multi-Threshold CMOS, and Active Body Bias. The use these techniques imply new challenges in validation of designs as new power states are created. We dive into details of several new verification issues that can potentially lead to a re-spin and are a direct result of using these techniques. These issues have been seen while working with chips used in cell phones and other hand-held devices; they pose a real threat to any low power design in various application areas that plan to use these techniques.
