Currently, reference design platforms such as RD-N2, RD-N1-Edge, RD-V1-MC, RD-V1 and SGI-575 utilize "css/sgi" as the common source directory. The "sgi" prefix originated from the System Guidance for Infrastructure (SGI) and was initially associated with the SGI-575 platform. However, subsequent platforms released were under the Neoverse Reference Design product name. To align with the Neoverse Reference Design nomenclature, rename the common source directory from "css/sgi" to "css/neoverse_rd" and update all file prefixes from "sgi" to "nrd."
