This is a 42nd video on VLSI Physical Design Series. In this video we have explained about different kind of vt cell variants and must be understood thoroughly.

Please ask your doubts in comments.

I think main change is oxide thickness below the gate changes for lvt, svt & hvt, doping concentration also helps little bit, because threshold voltage VT is a function of --> (oxide thickness tox, source to bulk voltage Vsb, Doping concentration Na or Nd).

Sir how we can find synchronous and asynchronous paths in the design

Hi sir, I have a question about which doping are you referring to, the substrate doping or the drain/source doping?

How to identify which cells are lvt / htv from library ? How to guide tool to use lvt cell instead of hvt ? Thanks in advance

Why the size is not change while swapping the vt's
