The GRLIB IP library has support for Microsemi RTG4 devices. This support consists of a techmap layer that wraps RTG4 specific technology elements such as memory macros and pads. GRLIB also contains a template design for the RTG4 Development Kit, bridges that allow to use the Microsemi FDDR memory controller and SerDes IP together with a LEON/GRLIB system, and infrastructure that automatically builds project files for Libero SoC. More information about GRLIB and Cobham Gaisler IP cores is available on the SoC library page.
Cobham Gaisler provides prebuilt bitstreams of the Microsemi RTG4 Development Kit LEON3 and LEON4 template design. These bitstreams are intended for evaluation of software running on a LEON3 or LEON4 SoC implemented in RTG4. To evaluate these designs, the following items are required:
The example design range is called LEON-RTG4-EX and includes the following IP cores:
