SC-LDPC codes with sub-block locality can be decoded locally at the level of\nsub-blocks that are much smaller than the full code block, thus providing fast\naccess to the coded information. The same code can also be decoded globally\nusing the entire code block, for increased data reliability. In this paper, we\npursue the analysis and design of such codes from both finite-length and\nasymptotic lenses. This mixed approach has rarely been applied in designing SC\ncodes, but it is beneficial for optimizing code graphs for local and global\nperformance simultaneously. Our proposed framework consists of two steps: 1)\ndesigning the local code for both threshold and cycle counts, and 2) designing\nthe coupling of local codes for best cycle count in the global design.\n
