Layer-Purpose Pair

Layers in PDKs roughly correspond to physical layers in the semiconductor fabrication process. In this schema, a “layer” is a pair: first, some major layer (like “the first metal layer”) and second, some sub-index into that layer distinguishing the various purposes objects serve on the major layor.
