Cobham Gaisler is a world leader in embedded computer systems for harsh environments, with footprints in many parts of the solar system. We provide the full ecosystem to support digital hardware design for mission critical System-on-a-Chip solutions. The IP cores and development tools support processors based on the SPARC and RISC-V architectures. In addition to this, a number of standard components are available.



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 Cobham Gaisler IP cores is available on the SoC library page.

Example designs

Cobham Gaisler provides 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:

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