Can threshold voltage and gate length be varied concurrently? Is it possible to consider simultaneous 3 sigma variations for both these parameters during modeling? Or these two parameters correlated (correlation coefficient must be considered)?

Welcome to AAC!

The general answer is yes. There are a number of factors that affect threshold voltage and gate length is one of them. How much gate length can affect threshold voltage depends on the process and gate length restrictions.
