A simple System-on-Chip built on an FPGA, originally targeted at Zhejiang University's SWORD4 FPGA experiment platform. It is designed to support simple operating systems developed by students; the first operating system running on this SoC is ZJUNIX.
Detailed documentation is currently in progress; a general description is provided in doc/SoC.md.
Follow these steps to create the SoC project from this repository:
-
Launch Vivado and open the TCL console. Note: This project is based on Vivado version 2016.2. Different versions of Vivado will produce different synthesis results, and it is possible for the design to fail to meet timing requirements.
-
Navigate to the
projectdirectory with thecdcommand. Note: The path to this directory should not contain spaces or non-ascii characters -
Run the following TCL commands (substitute <platform> with the target platform; currently N4DDR and SWORD4 are supported).
set project_platform <platform> source SoC.tcl
Example:
The script fileset.tcl contains lists of design sources for different platforms. rtl_common and header_common record shared RTL sources and verilog headers, respectively. rtl_<platform> and constr_<platform> record RTL sources(including IP cores) and constraints for <platform>. constr_<platform>_target specifies the target constraint file for <platform>. When adding/removing source files to/from the project, these variables should be modified accordingly.
