  • Systems and methods for concurrently testing master and slave devices in a system on a chip
    Patent number: 9645963
    Abstract: An integrated circuit includes a substrate, a master system on the substrate, a slave system on the substrate that is coupled to communicate with the master system, a first clock signal coupled to the master system, and a second clock signal coupled to the slave system. The master system is configured to isolate the slave system from the master system while a first test of the master system is conducted in parallel with a second test of the slave system. The master system uses the first clock signal during the first test and the slave system uses the second clock signal during the second test.
