HVT LVT SVT Cells

HVT = high V threshold. Can be used in the path where timing is not critical. So by using HVT cells we can save power.

LVT - Low V threshold. One should use these cells in timing critical paths. These cells are fast but , comsumes more power due to its leakage. So it will consume more power. So use only when timing is critical.


SVT- Standard V threshold. Best of both world. Medium delay and medium power requirment. So if timing is not met by small magin with HVT, you should try with SVT. And at last LVT.

  2. Can anyone relate it with delay ND temperature etc

    1. HVT --> Higher threshold Voltage --> More Delay.
      LVT --> Lower threshold Voltage --> Less Delay.

      * For best timing use the LVT cells.
      * For IR drop issue use the HVT cells.
