LiteScope is a small footprint and configurable embedded logic analyzer that you
|
|
|
|
|
can use in your FPGA and aims to provide a free, portable and flexible
|
2015-01-27 15:08:24 -05:00
|
|
|
alternatve to vendor's solutions!
|
|
|
|
|
|
|
|
|
|
LiteScope is part of LiteX libraries whose aims are to lower entry level of complex
|
|
|
|
|
FPGA IP cores by providing simple, elegant and efficient implementations of
|
|
|
|
|
components used in today's SoC such as Ethernet, SATA, PCIe, SDRAM Controller...
|
|
|
|
|
|
|
|
|
|
The core uses simple and specific streaming buses and will provides in the future
|
|
|
|
|
adapters to use standardized AXI or Avalon-ST streaming buses.
|
|
|
|
|
|
|
|
|
|
Since Python is used to describe the HDL, the core is highly and easily
|
|
|
|
|
configurable.
|
|
|
|
|
|
|
|
|
|
LiteScope uses technologies developed in partnership with M-Labs Ltd:
|
|
|
|
|
- Migen enables generating HDL with Python in an efficient way.
|
|
|
|
|
- MiSoC provides the basic blocks to build a powerful and small footprint SoC.
|
|
|
|
|
|
|
|
|
|
LiteScope can be used as a Migen/MiSoC library (by simply installing it
|
|
|
|
|
with the provided setup.py) or can be integrated with your standard design flow
|
|
|
|
|
by generating the verilog rtl that you will use as a standard core.
|
|
|
|
|
|
|
|
|
|
LiteScope produces "vcd" files that can be read in your regular waveforms viewer.
|
|
|
|
|
|
|
|
|
|
Since LiteScope also provides a UART <--> Wishbone brige so you only need 2
|
|
|
|
|
external Rx/Tx pins to be ready to debug or control all your Wishbone peripherals!
