Thanks! It's very useful.

HELLO!!

libMetric™ employs a Least Squares (LS) Regression model to construct a multidimensional response surface. Instead of simple linear interpolation, the tool fits a high-order polynomial or spline to the existing timing arcs. This enables the engine to accurately predict "off-grid" delay values caused by complex Miller effects or threshold voltage variations, ensuring that the calculated number of insertion stages remains physically valid across the entire operational envelope.
