HVt_LVt_SVt

Generally, High-Vt (HVt) libraries are better for power and worse for timing, while Low-Vt (LVt) libraries are much better for timing, but are very leaky. With the availability of libraries containing multiple channel lengths, it is possible to achieve better timing and lower leakage with a Standard-Vt (SVt) cell with a longer channel than an HVt cell with standard channel length.
