This leon3 design is tailored to the Xilinx SP605 Spartan6 board

Simulation and synthesis
------------------------

The design uses the Xilinx MIG memory interface with an AHB-2.0
interface. The MIG source code cannot be distributed due to the
prohibitive Xilinx license, so the MIG must be re-generated with
coregen before simulation and synthesis can be done.

To generate the MIG and install tne Xilinx unisim simulation
library, do as follows:

make mig
make install-secureip

This will ONLY work with ISE-13.2 installed, and the XILINX variable
properly set in the shell. To synthesize the design, do

make ise

and then

make ise-prog-fpga

to program the FPGA.

Design specifics
----------------

* System reset is mapped to the CPU RESET button

* The AHB and processor is clocked by a 60 MHz clock, generated
from the 33 MHz SYSACE clock using a DCM. You can change the frequency
generation in the clocks menu of xconfig. The DDR3 (MIG) controller
runs at 667 MHz.

* The GRETH core is enabled and runs without problems at 100 Mbit.
Ethernet debug link is enabled and has IP 192.168.0.51.
1 Gbit operation is also possible (requires grlib com release),
uncomment related timing constraints in the leon3mp.ucf first.

* 16-bit flash prom can be read at address 0. It can be programmed
with GRMON version 1.1.16 or later.

* DDR3 is working with the provided Xilinx MIG DDR3 controller.
If you want to simulate this design, first install the secure
IP models with:

make install-secureip

Then rebuild the scripts and simulation model:

make distclean vsim

Modelsim v6.6e or newer is required to build the secure IP models.
Note that the regular leon3 test bench cannot be run in simulation
as the DDR3 model lacks data pre-load.

* The application UART1 is connected to the USB/UART connector

* The SVGA frame buffer uses a separate port on the DDR3 controller,
and therefore does not noticeably affect the performance of the processor.
Default output is analog VGA, to switch to DVI mode execute this
command in grmon:

i2c dvi init_l4itx_vga

* The JTAG DSU interface is enabled and accesible via the USB/JTAG port.
Start grmon with -xilusb to connect.

* Output from GRMON is:

$ grmon -xilusb -u
