Integrated circuit and a method for secure testing |
摘要 |
An integrated circuit that includes a controller and multiple internal circuitries, whereas the integrated circuit is characterized by further including a security mode determination unit that includes multiple one time programmable components for defining a security mode out of multiple possible security modes, whereas a selected circuitry mode affects access to an internal circuitry. A method for testing an integrated circuit, the method includes: receiving a request to access an internal circuitry; and responding to the request in view of a defined security mode; whereas the method is characterized by a stage of defining a security mode of a debug circuit out of multiple security modes, whereas the definition is responsive to at least a state of multiple one time programmable components.
