Introduction

The LEON5 processor and the GRLIB IP library has support for Microchip PolarFire FPGAs. This support consists of a techmap layer that wraps specific technology elements such as memory macros and pads. GRLIB also contains a template designs for developments boards such as the PolarFire FPGA Splash Kit and infrastructure that automatically builds project files for Libero SoC and synthesis tools such as Mentor Precision Hi-Rel and Synopsys Synplify Premier. More information about GRLIB and our IP cores is available on the SoC library page.

Example designs

We provide prebuilt bitstreams of the PolarFire FPGA Splash Kit LEON5 template design. These bitstreams are intended for evaluation of software running on a LEON5 SoC. To evaluate these designs, the following items are required:

• PolarFire FPGA Splash Kit (currently bitstreams are only available for the MPF300_ES device) 
• Workstation with GNU/Linux or Microsoft Windows
• Microchip software to program FPGA
• Bitstream, available further down on this page
• GRMON3 debug monitor - GRMON3 evaluation version (version 3.2.16 or later required)

The example design range is called LEON-PF-EX:

• LEON-PF User's Manual
• LEON-PF Quick Start Guide
• LEON-PF FPGA configuration files
• LEON5 documentation in the GRLIB IP Library User´s Manual
