Power consumption has become one of the most important differentiating factors for semiconductor products. Voltage is the strongest handle for managing chip power consumption. We look in detail at some of key power management techniques such as power gating, adaptive voltage scaling and active body-bias that leverage voltage as a handle. We discuss the implications of power management architecture...
Dynamic verification, the use of simulation to determine design correctness, is widely used due to its tractability for large designs. A serious limitation of dynamic techniques is the difficulty in determining whether or not a test sequence is sufficient to detect all likely design errors. Coverage metrics are used to address this problem by providing a set of goals to be achieved during the simulation...
Functional coverage models which measure the sufficiency of test stimuli are essential to the verification process. A key source of difficulty in their deployment emanates from the manual and imprecise nature of their development process and the lack of a sound measure of their quality. A functional coverage model can be considered complete only if it accurately reflects the behavior of the Design...
