Development Environment

This page describes the development environment required for RSD.
The environment depends on what you want to do.
This page considers the following three purposes.

• Software simulation
• Boot on Xilinx Zynq FPGA boards
• Synthesis for ASIC (experimental)

Please read this page carefully and setup required OS, tools, and packages.
The version of each software that we tested is also listed, but RSD could work with other versions.

Operating System

Cygwin on Windows or Linux can be used, depending on your purpose.
Only x86-64 machines are tested.

	OS	Tested version
Software simulation	Windows Linux	Cygwin on Windows 10 Debian 8 Ubuntu 18.04
Boot on Xilinx Zynq FPGA boards	Linux	Debian 8 Ubuntu 18.04
Synthesis for ASIC	Linux	Debian 8 Ubuntu 18.04

Necessary Dependencies

The followings are required for all the three purposes on both Windows and Linux.

	Tested version
Git
Python 3	3.4.2
RISC-V GCC cross compiler	8.1.0

For Software Simulation

One of the followings is also required to simulate RSD on software simulators.

	Tested version
Mentor QuestaSim	2019.4.2
Mentor ModelSim
Verilator	4.026 3.922
Xilinx Vitis	2019.2.1

For Boot on Xilinx Zynq FPGA Boards

The followings are also required to boot RSD on Xilinx Zynq FPGA boards.

	Tested version
Synopsys Synplify	M-2017.03-SP1

In addition, run the following commands to install necessary packages via apt-get.

sudo ln -s /usr/bin/make /usr/bin/gmake  # If you use Ubuntu    
sudo apt-get install u-boot-tools ntp device-tree-compiler    

For Synthesis for ASIC (experimental)

The following is also required to synthesize RSD for ASIC.

	Tested version
Synopsys Design Compiler	O-2018.06-SP4

Recommended Tools

• Pipeline viewer Konata
  • Download and extract the pre-built binary archive.
• Visual Studio Code
  • Please install SystemVerilog extension after introduction.
  • We strongly recommend to use svls-vscode.
