GRLIB: VHDL IP library for fault-tolerant SoC

GRLIB, a VHDL IP library developed and maintained by Frontgrade Gaisler, offers reusable VHDL IP cores that facilitate the development of system-on-chip designs. These cores, which include processors, memory controllers, bus infrastructure, and peripherals, support the creation of both simple controllers and complex system-on-chip designs with fault tolerance features. Designed to be flexible and easy to use, GRLIB is widely used in the space industry. It is vendor-independent, with built-in support for various EDA tools and target technologies. It also includes template designs for popular development boards from major vendors. The IP cores included have extensive heritage, reducing the time and effort required for design and verification, and ensuring reliable and high-quality systems.This digest offers an overview of GRLIB and highlights the latest additions to the library, the SPARC LEON5 processor, the RISC-V NOEL-V processor, a high-speed serial link controller supporting WizardLink and SpaceFibre, the GRSCRUB FPGA supervisor, a NAND Flash memory controller, and a DDR2/DDR3 memory controller with strong EDAC capabilities.
