摘要： A wrapped core linking module for accessing system on chip test includes a link control register that stores link control configuration between cores in a scan path of a system on chip according to control signals applied from an outside boundary. A link control register controller controls a shift and update link configuration by activating the link control register. A switch switches the scan path between wrapped cores based on the link control configuration of the link control register. An output logic connects the link control register to a test data out (TDO) of the chip in case of testing on chip or cores of system on chip.
