Abstract

There is provided boundary cells arranged to form a boundary between a first power domain and a second power domain. Each power domain has an associated power rail. The boundary cells physically and electrically isolate functional cells of the first power domain from functional cells of the second power domain. Each boundary cell comprises a first well tap having a first conductivity type provided within a first region of a substrate, wherein the first well tap is electrically connected to a ground rail, and a second well tap having a second conductivity type provided within a second region of the substrate, wherein the second well tap is electrically connected to the power rail of the first power domain. The power rails of each power domain extend partially across the boundary cell, the first power rail being physically and electrically isolated from the second power rail.
