LEON-RTG4

The LEON processor and the GRLIB IP library have support for  RTG4 devices. We provide prebuilt bitstreams for the Microsemi RTG4 Development Kit. These bitstreams are intended for evaluation of software running on a LEON3 or LEON4 SoC implemented in RTG4.

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 our IP cores is available on the SoC library page.

To evaluate the example bitstreams, the following items are required:

• Microsemi RTG4 Development Kit FPGA board
• Workstation with GNU/Linux or Microsoft Windows
• Microsemi software to program FPGA
• Bitstream, available further down on this page
• GRMON debug monitor - evaluation version (version 3.0.6 or later)
