Patent number: 9927490Abstract: An integrated circuit senses attempts to access security-related data stored in registers connectable into a scan chain when the attempt includes locally and selectively asserting a scan-enable signal at a corresponding branch of the scan-enable tree when the integrated circuit is in a secure functional mode. When such an attempt is detected, the integrated circuit (i) generates a security warning that causes a reset of the security-related data and/or (ii) engages a bypass switch to disconnect the scan chain from the respective output terminal to preclude the security-related data from being shifted out of the IC via the scan chain.Type: GrantFiled: July 3, 2016Date of Patent: March 27, 2018Assignee: NXP USA, INC.Inventors: Pingli Hao, Wanggen Zhang

Patent number: 9805826Abstract: An integrated circuit (IC) having a memory for storing data also has a memory built in self-test (MBIST) unit coupled to the memory for testing an operation of the memory. A test interface provides test data. Flip-flops of the IC are connected together into at least one serial scan chain. The test interface unit receives test data including MBIST configuration data. The MBIST unit, in a first mode, tests the memory based on the MBIST configuration data at least partly in parallel with a scan test using the scan chain. Thus, both the memory and the logic circuitry can be tested in parallel.Type: GrantFiled: November 20, 2015Date of Patent: October 31, 2017Assignee: NXP USA,INC.Inventors: Weiwei Sang, Wanggen Zhang

Patent number: 9726724Abstract: An integrated circuit that includes a processor also has an on-chip current test circuit that indirectly measures quiescent current in the processor. A supply voltage pin of the integrated circuit receives a supply voltage from an external test unit to provide power to the processor. The on-chip test circuit measures a voltage change across the processor during a predetermined test period T when the processor is isolated from the supply voltage and the clock signal is stopped. The voltage change provides an indication of quiescent current corresponding to the processor.Type: GrantFiled: November 26, 2014Date of Patent: August 8, 2017Assignee: NXP USA, INC.Inventors: Xiuqiang Xu, Yin Guo, Shayan Zhang, Wanggen Zhang, Xu Zhang, Yizhong Zhang
