This board is provided as a kit as follows:

  • GR-XC6S-LX75 Board
  • Power Supply (100-240VAC -> 5VDC)
  • Low Cost JTAG Programming Cable
  • Interface cables (Ethernet, USB, Serial)
  • CD documentation

The Documentation includes: user's manual, complete schematics, necessary .ucf files for Xilinx place&route tools and example GRLIB/Leon3 configurations.

For LEON processor development, the RCC/BCC cross-compiler system, Evaluation Version of GRMON and Open Source version of GRLIB/LEON3 VHDL model sources can be downloaded from the Aeroflex Gaisler web-page. For information on the GRLIB/Leon3 VHDL model, software tools and their licensing, please contact Aeroflex Gaisler

ERRATA: This board includesa a USB interface implemented with an ST-Ericsson ISP1504A USB PHY interface chip. While this interface chip is generally compatible with the Gaisler GRLIB/LEON3 IP core for USB, the input and output timing characteristics of the Xilinx Spartan 6 chip used on this board mean that it is not possible to get a satisfactory timing so that the core will function reliably with this Xilinx Spartan 6 chip. If you require to use USB with Aeroflex Gaisler's GRLIB/LEON3 USB core, please contact
