A system may include a first power domain defined by a first supply rail and a first ground rail, a second power domain defined by a second supply rail and a second ground rail, and a configurable switch coupled between the first ground rail and the second ground rail such that when the configurable switch is enabled, the first ground rail and the second ground rail are electrically shorted to one another and when the configurable switch is disabled, the first ground rail and the second ground rail are electrically isolated from one another.
