Detailed Description

A range table is a table of values that are indexed by ranges. It can be viewed as a map from contiguous ranges [a,b] to v.

More information about the format of a range table can be found at: https://avlsi.csl.yale.edu/act/doku.php?id=config:layout&s[]=range&s[]=table::range_tables This is used to hold design rules where the rule is indexed by the value of another parameter (e.g. minimum width of a metal depends on the length of the metal wire)
