What is Golden Hardware Reference Design (GHRD) and Golden System Reference Design (GSRD) for FPGA?

Golden Hardware Reference Design (GHRD) and Golden System Reference Design (GSRD) are typically employed in FPGA-based solutions, serving a broad range of applications, particularly in embedded systems. These reference designs are crucial for customers as they provide a reliable benchmark that significantly reduces development time. Additionally, they offer the flexibility for customers to tailor FPGA solutions to their specific hardware platforms and software requirements. I created the comparative table below between GHRD and GSRD because I couldn't find any resources that explained the differences in a straightforward, comparative format.
