-
- A generic and configurable SATA1/2/3 core
- developed in partnership with M-Labs Ltd & HKU
-
-[> Features
-------------------
-PHY:
- - OOB, COMWAKE, COMINIT.
- - ALIGN inserter/remover and bytes alignment on K28.5.
- - 8B/10B encoding/decoding in transceiver.
- - Errors detection and reporting.
- - 1.5 / 3.0 / 6.0GBPs supported speeds.
- - 37.5 / 75 / 150MHz system clock.
-Core:
- Link:
- - CONT inserter/remover.
- - Scrambling/Descrambling of data.
- - CRC inserter/checker.
- - HOLD insertion/detection.
- - Errors detection and reporting.
- Transport/Command:
- - Easy to use user interface (Can be used with or without CPU).
- - 48 bits sector addressing.
- - 3 supported commands: READ_DMA(_EXT), WRITE_DMA(_EXT), IDENTIFY_DEVICE.
- - Errors detection and reporting.
-
-Frontend:
- - Configurable crossbar (simply use core.crossbar.get_port() to add a new port!)
- - Ports arbitration transparent to the user.
- - Synthetizable BIST.
-
-[> Getting started
-------------------
-1. Install Python3 and Xilinx's Vivado software.
-
-2. Obtain Migen and install it:
- git clone https://github.com/enjoy-digital/migen
- cd migen
- python3 setup.py install
- cd ..
-
-3. Obtain Miscope and install it:
- git clone https://github.com/enjoy-digital/miscope
- cd miscope
- python3 setup.py install
- cd ..
-
-4. Obtain MiSoC:
- git clone https://github.com/enjoy-digital/misoc --recursive
-
-5. Copy lite-sata in working directory and move to it.
-
-6. Build and load design:
- make all
-
-7. Test design:
- go to test directory and run:
- python3 bist.py
-
-[> Simulations :
- Simulations are avalaible in ./lib/sata/test:
- - crc_tb
- - scrambler_tb
- - phy_datapath_tb
- - link_tb
- - command_tb
- - bist_tb
- hdd.py is a HDD model implementing all SATA layers.
- To run a simulation, move to ./lib/sata/test and run:
- make simulation_name
-
-[> Tests :
- A synthetisable BIST is provided and can be controlled with ./test/bist.py
- By using Miscope and the provided ./test/test_link.py example you are able to
- visualize the internal logic of the design and even inject the captured data in
- the HDD model!

+[> Intro
+--------
+LiteX is an alternative to Migen/MiSoC maintained and used by Enjoy-Digital
+to build our cores, integrate them in complete SoC and load/flash them to
+the hardware and experiment new features.
+
+The structure of LiteX is kept close to Migen/MiSoC to ease collaboration
+between projects and efforts are made to keep cores developed with LiteX
+compatible with Migen/MiSoC.
+
+[> License
+----------
+LiteX is Copyright (c) 2012-2017 Enjoy-Digital under BSD Lisense.
+Since it is based on Migen/MiSoC, please also refer to LICENSE file in gen/soc
+directory or git history to get correct copyrights.
+
+[> Sub-packages
+---------------
+gen:
+ Provides specific or experimental modules to generate HDL that are not integrated
+ in Migen.
+
+build:
+ Provides tools to build FPGA bitstreams (interface to vendor toolchains) and to
+ simulate HDL code or full SoCs.
+
+soc:
+ Provides definitions/modules to build cores (bus, bank, flow), cores and tools
+ to build a SoC from such cores.
+
+boards:
+ Provides platforms and targets for the supported boards.
+
+[> Quick start guide
+--------------------
+0. If cloned from Git without the --recursive option, get the submodules:
+ git submodule update --init
+
+1. Install Python 3.3+ and FPGA vendor's development tools and JTAG tools.
+
+2. Compile and install binutils. Take the latest version from GNU.
+ mkdir build && cd build
+ ../configure --target=lm32-elf
+ make
+ make install
+
+3. (Optional, only if you want to use a lm32 CPU in you SoC)
+ Compile and install GCC. Take gcc-core and gcc-g++ from GNU
+ (version 4.5 or >=4.9).
+ rm -rf libstdc++-v3
+ mkdir build && cd build
+ ../configure --target=lm32-elf --enable-languages="c,c++" --disable-libgcc \
+ --disable-libssp
+ make
+ make install
+
+4. Build the target of your board...:
+ Go to boards/targets and execute the target you want to build
+
+5. ... and/or install Verilator and test LiteX on your computer:
+ Download and install Verilator: http://www.veripool.org/
+ Install libevent-devel / json-c-devel packages
+ Go to boards/targets
+ ./sim.py
+
+6. Run a terminal program on the board's serial port at 115200 8-N-1.
+ You should get the BIOS prompt.
