This leon3 design is tailored to the Xilinx Virtex-7 VC707 board
http://www.xilinx.com/vc707
Note: This design requires that the GRLIB_SIMULATOR variable is
correctly set. Please refer to the documentation in doc/grlib.pdf for
additional information.
Note: The Vivado flow and parts of this design are still
experimental. Currently the design configuration should be left as-is.
Note: You must have Vivado 2014.4.1 in your path for the make targets to work.
The XILINX_VIVADO variable must be exported for the mig_7series target
to work correctly: export XILINX_VIVADO
Simulation and synthesis
------------------------
The design uses the Xilinx MIG memory interface with an AHB-2.0
interface and Xilinx SGMII PHY Interface. The MIG or the SGMII PHY
source code cannot be distributed due to the prohibitive Xilinx
license, so the MIG and/or the SGMII must be re-generated with
Vivado before simulation and synthesis can be done.
Xilinx MIG and SGMII interface will automatically be generated when
Vivado is launched
To simulate using XSIM and run systest.c on the Leon design using the memory
controller from Xilinx use the make targets:
make soft
make vivado-launch
To simulate using Modelsim/Aldec and run systest.c on the Leon design using
the memory controller from Xilinx use the make targets:
make map_xilinx_7series_lib
make sim
make mig_7series
make sgmii_7series
make sim-launch
To simulate using the Aldec Riviera WS flow use the following make targets:
make riviera_ws # creates riviera workspace
make map_xilinx_7series_lib # compiles and maps xilinx sim libs
make mig_7series # generates MIG IP and adds to riviera project
make sgmii_7series # same for SGMII adapter
make riviera # compile full project
make riviera-launch # launch simulation
To synthesize the design, do
make vivado
and then use iMPACT programming tool:
make ise-prog-fpga
to program the FPGA.
After successfully programmed the FPGA using the target 'ise-prog-fpga' user might
have to press the 'CPU RESET' button in order to successfully complete the calibration
process in the MIG. Led 1 and led 2 should be constant green if the Calibration
process has been successful.
If user tries to connect to the board and the MIG has not been calibrated successfully
'grmon' will output:
$ grmon -xilusb -u -nb

Exiting GRMON
The MIG and SGMII IP can be disabled either by deselecting the memory controller
and Gaisler Ethernet interface in 'xconfig' or manually editing the config.vhd file.
When no MIG and no SGMII block is present in the system normal GRLIB flow can be
used and no extra compile steps are needed. Also when when no MIG is present it
is possible to control and set the system frequency via xconfig.
Note that the system frequency can be modified via Vivado when the MIG is present
by modifying within specified limits for the MIG IP.
Compiling and launching modelsim when no memory controller and no ethernet interface
is present using Modelsim/Aldec simulator:
make vsim
make soft
make vsim-launch
Simulation options
------------------
All options are set either by editing the testbench or specify/modify the generic
default value when launching the simulator. For Modelsim use the option "-g" i.e.
to enable processor disassembly to console launch modelsim with the option: "-gdisas=1"
USE_MIG_INTERFACE_MODEL - Use MIG simulation model for faster simulation run time
(Option can now be controlled via 'make xconfig')
disas - Enable processor disassembly to console
DEBUG - Enable extra debug information when using Micron DDR3 models
Design specifics
----------------
* Synthesis should be done using Vivado 2014.4.1 or newer
* The DDR3 controller is implemented with Xilinx MIG 7-Series 2.0 and
runs of the 200 MHz clock. The DDR3 memory runs at 400 MHz
(DDR3-800). grmon-2.0.30-74 or later is needed to detect the
DDR3 memory.
* The AHB clock is generated by the MMCM module in the DDR3
controller, and can be controlled via Vivado. When the
MIG DDR3 controller isn't present the AHB clock is generated
from CLKGEN, and can be controlled via xconfig
* System reset is mapped to the CPU RESET button
* DSU break is mapped to GPIO east button
* LED 0 indicates processor in debug mode
* LED 1 indicates processor in error mode, execution halted
* LED 2 indicates DDR3 PHY initialization done (Only valid when MIG is present)
* LED 3 indicates internal PLL has locked (Only valid when MIG isn't present)
* 16-bit flash prom can be read at address 0. It can be programmed
with GRMON version 2.0.30-74 or later.
* The application UART1 is connected to the USB/RS232 connector if
switch 5, located on the DIP Switch SW2 of the board, is set to OFF.
* The AHB UART can be enabled by setting switch 5 to ON.
Since the board is equipped with one USB/RS232 connector, APB UART1 and
AHB UART cannot be used at the same time.
* The JTAG DSU interface is enabled and accesible via the JTAG port.
Start grmon with -xilusb to connect.
* Output from GRMON is:
grmon -xilusb
