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 four purposes.
  • Functional simulation
  • Boot on Xilinx Zynq FPGA boards
  • Post-Synthesis Simulation For FPGA
  • 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

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

	OS	Tested version
Functional simulation	Linux	Debian 8 Ubuntu 20.04
Boot on Xilinx Zynq FPGA boards	Linux	Debian 8 Ubuntu 20.04
Post-Synthesis Simulation For FPGA	Linux	Debian 8 Ubuntu 20.04
Synthesis for ASIC	Linux	Debian 8 Ubuntu 20.04

Necessary Dependencies

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

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

For Functional Simulation

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

	Tested version
Mentor QuestaSim	2019.4.2
Verilator	4.026 3.922
Xilinx Vitis (including Vivado)	2019.2.1

For Boot on Xilinx Zynq FPGA Boards / Post-synthesis Simulation For FPGA

• The followings are also required to boot RSD on Xilinx Zynq FPGA boards or run post-synthesis simulation for FPGA.

	Tested version
Xilinx Vitis (including Vivado)	2019.2.1

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

alias gmake=make  # If you use Ubuntu    
sudo apt-get install u-boot-tools ntp device-tree-compiler flex openssl   
sudo apt-get install libtinfo5

Synplify (Optional, but recommended)

• RSD can be synthesized using Synopsys Synplify.
  • In our evaluation, Synplify+Vivado provided better operating frequency than Vivado-only.
• We therefore recommend to use Synplify if you have its license.
• The following is required for running the Synplify+Vivado design on Xilinx Zynq FPGA boards.

	Tested version
Synopsys Synplify	M-2017.03-SP1

• In addition, the following is required for post-synthesis simulation for the Synplify+Vivado design.

	Tested version
Mentor QuestaSim	2019.4.2

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.
