Integrated Circuit Metering: Protecting Your Intellectual Property in the World of Chips

Chip manufacturing has become an increasingly complex and costly process. Today, most design companies operate under a fabless model, focusing on innovation and outsourcing production to specialized foundries. While economically advantageous, this approach exposes designs to significant risks, such as unauthorized reproduction—commonly known as overbuilding. Fortunately, advanced integrated circuit metering, or hardware metering, offers a
