How Do You Reduce Power Dissipation Using High Vt And Low Vt On Your

1.	How Do You Reduce Power Dissipation Using High Vt And Low Vt On Your Design?
Answer» Use HVT cells for timing paths having +ve SLACKS. Use LVT cells for timing paths having -ve slacks. HVT cells have a larger delay but less leakage. +ve slack in a design is not useful as having only some paths working faster will not help overall design. We are good if the slack is 0. In such cases give up the slack by using HVT cells but gain on POWER dissipation. LVT cells are very FAST but very LEAKY. Limit the use of LVT cells to only those paths that have difficulty in closing time.
