Abstract:
A method, an integrated circuit structure, and an associated design structure for the integrated circuit structure have a plurality of logic blocks, at least one of which is a redundant logic block. In addition, the structure includes a logic built-in self test device (LBIST) operatively connected to the logic blocks that determines the functionality of each of the logic blocks. An array of memory elements is included within the structure and is operatively connected to the logic blocks. At least one of the memory elements comprises a redundant memory element. The structure also includes an array built-in self test device (ABIST) operatively connected to the array of memory elements that determines the functionality of each of the memory elements. One feature is the use of a single controller operatively connected to the register, the logic blocks, and the memory elements. The single controller repairs both the logic blocks elements that have failing functionality and the memory elements that have failing functionality.
