摘要： A system and method are provided on one or more companion chips having a plurality of cores. Each core has core circuitry and a test interface for carrying out tests in relation to the core circuitry. The test interface has an address register to hold an address of the core and address determination circuitry. The address determination circuitry is configured to compare an address received on an address line to the address held in the address register to determine whether a core is being addressed. The address determination circuitry is also configured to direct the test interface to carry out a testing operation in response to the determination.

摘要： An integrated circuit can have plural core circuits, each having a test access port that is defined in IEEE standard 1149.1. Access to and control of these ports is though a test linking module. The test access ports on an integrated circuit can be arranged in a hierarchy with one test linking module controlling access to plural secondary test linking modules and test access ports. Each secondary test linking module in turn can also control access to tertiary test linking modules and test access ports. The test linking modules can also be used for emulation.

摘要： A heterogeneous multi-core integrated circuit includes first and second sets of processor cores and corresponding first and second test access ports (TAPs). The first and second TAPs are connected to corresponding first and second debug ports by way of corresponding first and second TAP controllers. A debug control circuit is connected between the first and second TAP controllers and the first and second debug ports. Based on external configuration signals, the debug control circuit configures the connections between the first and second TAP controllers and the first and second debug ports according to predetermined configuration modes, which allows flexibility in debugging the heterogeneous multi-core integrated circuit.

摘要： In some embodiments, a computer-implemented method includes receiving, in a processor, a device description code identifying components of a device and connections between the components, wherein some of the components and connections form boundary cells used for testing the device. The method can include processing, in the processor, the device description code to determine that the components and the connections meet a standard governing components and connections necessary for the boundary cells. The method can also include traversing the connections between the components to determine that the connections meet the standard, and reporting, via one or more output devices, that the device complies with the standard.

摘要： An integrated chip architecture is provided which allows for efficiently testing multiple cores included in the integrated chip architecture. In particular, the provided approach enables the test time and the number of required Input/Output test pins is nearly independent from the number of cores included in the multicore chip. The presented embodiments provide a multicore chip architecture which allows for providing input data to the multiple cores in parallel for simultaneously testing the multiple cores, and analyzing the resulting multiple test outputs on chip. As a result of this analysis embodiments may store on chip an indication for those cores that have not successfully passed the test.
