19 LiteScope is small footprint and configurable embedded logic analyzer that you
20 can use in your FPGA and aims to provide a a free, portable and flexible
21 alternatve to vendor's solutions!
23 LiteScope is part of LiteX libraries whose aims are to lower entry level of complex
24 FPGA IP cores by providing simple, elegant and efficient implementations of
25 components used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller...
27 The core uses simple and specific streaming buses and will provides in the future
28 adapters to use standardized AXI or Avalon-ST streaming buses.
30 Since Python is used to describe the HDL, the core is highly and easily
33 LiteScope uses technologies developed in partnership with M-Labs Ltd:
34 - Migen enables generating HDL with Python in an efficient way.
35 - MiSoC provides the basic blocks to build a powerful and small footprint SoC.
37 LiteScope can be used as a Migen/MiSoC library (by simply installing it
38 with the provided setup.py) or can be integrated with your standard design flow
39 by generating the verilog rtl that you will use as a standard core.
41 LiteScope produces "vcd" files that can be read in your regular waveforms viewer.
43 Since LiteScope also provides a UART <--> Wishbone brige so you only need 2
44 external Rx/Tx pins to be ready to debug or control all your Wishbone peripherals!
48 - IO peek and poke with LiteScopeIO
49 - Logic analyser with LiteScopeLA:
50 - Various triggering modules: Term, Range, Edge (add yours! :)
51 - Run Length Encoder to "compress" data and increase recording depth
54 - Data storage in block rams
56 [> Possible improvements
57 -------------------------
58 - add standardized interfaces (AXI, Avalon-ST)
59 - add protocols analyzers
60 - add signals injection/generation
62 - add storage in HDD with LiteSATA core (to be released soon!)
63 - add Ethernet Wishbone bridge
64 - add PCIe Wishbone bridge with LitePCIe (to be released soon!)
65 - ... See below Support and consulting :)

74 1. Install Python3 and your vendor's software
76 2. Obtain Migen and install it:
77 git clone https://github.com/m-labs/migen
79 python3 setup.py install
82 3. Obtain MiSoC and install it:
83 git clone https://github.com/m-labs/misoc --recursive
85 python3 setup.py install
88 Note: in case you have issues with Migen/MiSoC, please retry
90 https://github.com/enjoy-digital/misoc
91 https://github.com/enjoy-digital/migen
92 until new features are merged.
94 4. Obtain LiteScope and install it:
95 git clone https://github.com/enjoy-digital/litescope
97 5. Build and load test design:
98 python3 make.py -s [platform] all
99 Supported platforms are the one altready supported by Mibuild:
100 de0nano, m1, mixxeo, kc705, zedboard...
103 go to ./test directory and run:
108 XXX convert simulations

116 terms of this license, you are authorized to use LiteScope for closed-source
118 Even though we do not require you to do so, those things are awesome, so please
120 - tell us that you are using LiteScope
121 - cite LiteScope in publications related to research it has helped
122 - send us feedback and suggestions for improvements
123 - send us bug reports when something goes wrong
124 - send us the modifications and improvements you have done to LiteScope.

127 --------------------------
128 We love open-source hardware and like sharing our designs with others.
130 LiteScope is developed and maintained by EnjoyDigital.
132 If you would like to know more about LiteScope or if you are already a happy user
133 and would like to extend it for your needs, EnjoyDigital can provide standard
134 commercial support as well as consulting services.
136 So feel free to contact us, we'd love to work with you! (and eventually shorten
137 the list of the possible improvements :)
