Introduction

The LEON5 processor and the GRLIB IP library has support for Xilinx Kintex Ultrascale devices. 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 Xilinx Kintex UltraScale FPGA KCU105 Evaluation Kit and infrastructure that automatically builds project files for Xilinx Vivado 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 Xilinx Kintex UltraScale FPGA KCU105 Evaluation 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:

• Xilinx Kintex UltraScale FPGA KCU105 Evaluation Kit
• Workstation with GNU/Linux or Microsoft Windows
• Xilinx software to program FPGA
• Bitstream, available further down on this page
• GRMON3 debug monitor - GRMON3 evaluation version (version 3.2.16 or later is required)

The example design collection is called LEON-XCKU-EX:

• LEON-XCKU User's Manual
• LEON-XCKU Quick Start Guide
• LEON-XCKU Xilinx KCU105 FPGA configuration files
• LEON5 documentation in the GRLIB IP Library User´s Manual
