Synthesis lib, diff between hv/sv/lv?

[tutu_xie]

Hi, Vendor has 3 types lib,
They are high voltage, standard voltage, and low voltage.
And each contain fast/standard/slow.
What's the difference about vlotage, which should I use?
Thanks

HVT has low leakage and low speed
LVT has high leakage and high speed.
SVT is standard which sits somewhere between HVT and LVT.

As a thumb rule, start with HVT cells and when you fail timing, you can substitute HVT cells on a critical path with that LVT cells/SVT cells. This way you will save power. I'm assuming power and timing are critical for your design.
