3. Quickstart¶
This section is meant to serve as a quick-guide to setup RISCOF and perform a sample validation check
between spike
(DUT in this case) and SAIL-RISCV
(Reference model in this case). This guide
will help you setup all the required tooling for running riscof on your system.
If you would like to know how to build a plugin for your DUT please refer to the Building your Model Plugin section for more details.
If you have your DUT plugin ready and would like to run the riscv-arch-tests on it using RISCOF, please refer to section Running RISCV-ARCH-TESTS
3.1. Install Python¶
Ubuntu 17.10 and 18.04 by default come with python-3.6.9 which is sufficient for using riscv-config.
If you are are Ubuntu 16.10 and 17.04 you can directly install python3.6 using the Universe repository
$ sudo apt-get install python3.6
$ pip3 install --upgrade pip
If you are using Ubuntu 14.04 or 16.04 you need to get python3.6 from a Personal Package Archive (PPA)
$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt-get update
$ sudo apt-get install python3.6 -y
$ pip3 install --upgrade pip
You should now have 2 binaries: python3
and pip3
available in your $PATH.
You can check the versions as below
$ python3 --version
Python 3.6.9
$ pip3 --version
pip 20.1 from <user-path>.local/lib/python3.6/site-packages/pip (python 3.6)
The CentOS 7 Linux distribution includes Python 2 by default. However, as of CentOS 7.7, Python 3 is available in the base package repository which can be installed using the following commands
$ sudo yum update -y
$ sudo yum install -y python3
$ pip3 install --upgrade pip
For versions prior to 7.7 you can install python3.6 using third-party repositories, such as the IUS repository
$ sudo yum update -y
$ sudo yum install yum-utils
$ sudo yum install https://centos7.iuscommunity.org/ius-release.rpm
$ sudo yum install python36u
$ pip3 install --upgrade pip
You can check the versions
$ python3 --version
Python 3.6.8
$ pip --version
pip 20.1 from <user-path>.local/lib/python3.6/site-packages/pip (python 3.6)
3.1.1. Using Virtualenv for Python¶
Many a times users face issues in installing and managing multiple python versions. This is actually a major issue as many gui elements in Linux use the default python versions, in which case installing python3.6 using the above methods might break other software. We thus advise the use of pyenv to install python3.6.
For Ubuntu and CentosOS, please follow the steps here: https://github.com/pyenv/pyenv#basic-github-checkout
RHEL users can find more detailed guides for virtual-env here: https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/#create-env
Once you have pyenv installed do the following to install python 3.6.0:
$ pyenv install 3.6.0
$ pip3 install --upgrade pip
$ pyenv shell 3.6.0
You can check the version in the same shell:
$ python --version
Python 3.6.0
$ pip --version
pip 20.1 from <user-path>.local/lib/python3.6/site-packages/pip (python 3.6)
3.2. Install RISCOF¶
To install RISCOF, run this command in your terminal:
$ pip3 install git+https://github.com/riscv/riscof.git
This is the preferred method to install RISCOF, as it will always install the most recent stable release.
If you don’t have pip installed, this Python installation guide can guide you through the process.
Note
If you are using pyenv as mentioned above, make sure to enable that environment before performing the following steps.
$ pip3 install riscof
To update an already installed version of RISCOF to the latest version:
$ pip3 install -U riscof
To checkout a specific version of RISCOF:
$ pip3 install riscof==1.x.x
The sources for RISCOF can be downloaded from the Github repo.
You can clone the repository:
$ git clone https://github.com/riscv/riscof.git
Once you have a copy of the source, you can install it with:
$ cd riscof
$ pip3 install --editable .
3.3. Test RISCOF¶
Once you have installed RISCOF you can execute riscof --help
to print the help routine:
Usage: riscof [OPTIONS] COMMAND [ARGS]...
Options:
--version Show the version and exit.
-v, --verbose [info|error|debug]
Set verbose level
--help Show this message and exit.
Commands:
arch-test Setup and maintenance for Architectural TestSuite.
coverage Run the tests on DUT and reference and compare signatures
gendb Generate Database for the Suite.
run Run the tests on DUT and reference and compare signatures
setup Initiate Setup for riscof.
testlist Generate the test list for the given DUT and suite.
validateyaml Validate the Input YAMLs using riscv-config.
3.4. Install RISCV-GNU Toolchain¶
This guide will use the 32-bit riscv-gnu tool chain to compile the architectural suite. If you already have the 32-bit gnu-toolchain available, you can skip to the next section.
Note
The git clone and installation will take significant time. Please be patient. If you face issues with any of the following steps please refer to https://github.com/riscv-collab/riscv-gnu-toolchain for further help in installation.
$ sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev \
libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool \
patchutils bc zlib1g-dev libexpat-dev
$ git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
$ git clone --recursive https://github.com/riscv/riscv-opcodes.git
$ cd riscv-gnu-toolchain
$ ./configure --prefix=/path/to/install --with-arch=rv32gc --with-abi=ilp32d # for 32-bit toolchain
$ [sudo] make # sudo is required depending on the path chosen in the previous setup
$ sudo yum install autoconf automake python3 libmpc-devel mpfr-devel gmp-devel \
gawk bison flex texinfo patchutils gcc gcc-c++ zlib-devel expat-devel
$ git clone --recursive https://github.com/riscv/riscv-gnu-toolchain
$ git clone --recursive https://github.com/riscv/riscv-opcodes.git
$ cd riscv-gnu-toolchain
$ ./configure --prefix=/path/to/install --with-arch=rv32gc --with-abi=ilp32d # for 32-bit toolchain
$ [sudo] make # sudo is required depending on the path chosen in the previous setup
Make sure to add the path /path/to/install
to your $PATH in the .bashrc/cshrc
With this you should now have all the following available as command line arguments:
riscv32-unknown-elf-addr2line riscv32-unknown-elf-elfedit
riscv32-unknown-elf-ar riscv32-unknown-elf-g++
riscv32-unknown-elf-as riscv32-unknown-elf-gcc
riscv32-unknown-elf-c++ riscv32-unknown-elf-gcc-8.3.0
riscv32-unknown-elf-c++filt riscv32-unknown-elf-gcc-ar
riscv32-unknown-elf-cpp riscv32-unknown-elf-gcc-nm
riscv32-unknown-elf-gcc-ranlib riscv32-unknown-elf-gprof
riscv32-unknown-elf-gcov riscv32-unknown-elf-ld
riscv32-unknown-elf-gcov-dump riscv32-unknown-elf-ld.bfd
riscv32-unknown-elf-gcov-tool riscv32-unknown-elf-nm
riscv32-unknown-elf-gdb riscv32-unknown-elf-objcopy
riscv32-unknown-elf-gdb-add-index riscv32-unknown-elf-objdump
riscv32-unknown-elf-ranlib riscv32-unknown-elf-readelf
riscv32-unknown-elf-run riscv32-unknown-elf-size
riscv32-unknown-elf-strings riscv32-unknown-elf-strip
3.5. Install Plugin Models¶
This section will walk your throguh installing 2 important RISC-V reference models: Spike and SAIL. These are often used as reference models in RISCOF.
Alternative 1: Local Install
$ sudo apt-get install opam build-essential libgmp-dev z3 pkg-config zlib1g-dev
$ opam init -y --disable-sandboxing
$ opam switch create ocaml-base-compiler.4.06.1
$ opam install sail -y
$ eval $(opam config env)
$ git clone https://github.com/riscv/sail-riscv.git
$ cd sail-riscv
$ make
$ ARCH=RV32 make
$ ARCH=RV64 make
$ ln -s sail-riscv/c_emulator/riscv_sim_RV64 /usr/bin/riscv_sim_RV64
$ ln -s sail-riscv/c_emulator/riscv_sim_RV32 /usr/bin/riscv_sim_RV32
This will create a C simulator in c_emulator/riscv_sim_RV64
and
c_emulator/riscv_sim_RV32
. You will not need to add these paths in your $PATH
or an
alias to it to execute them from command line.
Alternative 2: Using Docker
For the convenience of the users, a docker image with all the necessary tools is available. The plugin also supports using this docker image to generate the reference signatures.
Warning
Ensure that docker is installed and configured properly before running this step.
The following command can be used to pull the docker image.
$ docker pull registry.gitlab.com/incoresemi/docker-images/compliance
$ sudo apt-get install device-tree-compiler
$ git clone https://github.com/riscv-software-src/riscv-isa-sim.git
$ cd riscv-isa-sim
$ mkdir build
$ cd build
$ ../configure --prefix=/path/to/install
$ make
$ [sudo] make install #sudo is required depending on the path chosen in the previous setup
Make sure to add the path /path/to/install
to your $PATH in the .bashrc/cshrc
Once installed, executing spike
on the terminal should print the following:
usage: spike [host options] <target program> [target options]
Host Options:
-p<n> Simulate <n> processors [default 1]
-m<n> Provide <n> MiB of target memory [default 2048]
-m<a:m,b:n,...> Provide memory regions of size m and n bytes
at base addresses a and b (with 4 KiB alignment)
-d Interactive debug mode
-g Track histogram of PCs
-l Generate a log of execution
-h Print this help message
-H Start halted, allowing a debugger to connect
--isa=<name> RISC-V ISA string [default RV64IMAFDC]
--pc=<address> Override ELF entry point
--hartids=<a,b,...> Explicitly specify hartids, default is 0,1,...
--ic=<S>:<W>:<B> Instantiate a cache model with S sets,
--dc=<S>:<W>:<B> W ways, and B-byte blocks (with S and
--l2=<S>:<W>:<B> B both powers of 2).
--extension=<name> Specify RoCC Extension
--extlib=<name> Shared library to load
--rbb-port=<port> Listen on <port> for remote bitbang connection
--dump-dts Print device tree string and exit
--disable-dtb Don't write the device tree blob into memory
--progsize=<words> Progsize for the debug module [default 2]
--debug-sba=<bits> Debug bus master supports up to <bits> wide accesses [default 0]
--debug-auth Debug module requires debugger to authenticate
3.6. Create Neccesary Env Files¶
In order to run tests via RISCOF you will need to provide the following items :
config.ini: This file is a basic configuration file following the ini syntax. This file will capture information like: name of the dut/reference plugins, path to the plugins, path to the riscv-config based yamls, etc. For more information on the contents and syntax please refer to the Config.ini Syntax section
dut-plugin directory: RISCOF requires that the DUT model for testing is presented in the form of a python plugin. The python plugin is nothing more than a python file which includes certain standard and defined functions to carry out the activities of test-compilation, execution and signature extraction. This python file name needs to be prefixed with
riscof_
and must be present in the dut-plugin directory. One can refer to the Python Plugin file section for more details on how to write this python file.The directory will also need to contain the riscv-config based isa and platform yamls which provide a definition of the DUT. These yamls will be used to filter tests that need to be run on the DUT.
Finally, an env directory will also need to be present in the dut-plugin directory, which contains the environment files like the
model_test.h
that is required to compile and run the tests on the DUT. Refer to the TestFormat spec for definition of macros that can be used in themodel_test.h
file. The env directory may also include other files like the linker script, post-processing scripts that the user may want.reference-plugin directory: Similar to the DUT plugin, RISCOF also expects a reference model plugin. The structure of the directory and files is the same as that of the DUT. However, the isa and platform yamls are not required since RISCOF will always pick the yamls from the DUT plugin for all purposes.
For sample templates of pre-built plugins please refer to List of Reference RISCOF Plugins.
To make things simpler, RISCOF generates standard pre-built templates for DUTs and Reference
Models for the user via the setup
command as shown below:
$ riscof setup --dutname=spike
The above command will generate the following files and directories in the current directory:
├──config.ini # configuration file for riscof
├──spike/ # DUT plugin templates
├── env
│ ├── link.ld # DUT linker script
│ └── model_test.h # DUT specific header file
├── riscof_spike.py # DUT python plugin
├── spike_isa.yaml # DUT ISA yaml based on riscv-config
└── spike_platform.yaml # DUT Platform yaml based on riscv-config
├──sail_cSim/ # reference plugin templates
├── env
│ ├── link.ld # Reference linker script
│ └── model_test.h # Reference model specific header file
├── __init__.py
└── riscof_sail_cSim.py # Reference model python plugin.
The generate template config.ini
will look something like this by default:
[RISCOF]
ReferencePlugin=sail_cSim
ReferencePluginPath=/path/to/riscof/sail_cSim
DUTPlugin=spike
DUTPluginPath=/path/to/riscof/spike
## Example configuration for spike plugin.
[spike]
pluginpath=/path/to/riscof/spike/
ispec=/path/to/riscof/spike/spike_isa.yaml
pspec=/path/to/riscof/spike/spike_platform.yaml
[sail_cSim]
pluginpath=/path/to/riscof/sail_cSim
If the SAIL binaries (i.e. riscv_sim_RV32
) are not in your $PATH you may want to add the following to the last line of the
above config:
PATH=<path_to_my_Sail_binaries>
To use the docker image(instead of a local sail installation) the sail_cSim
node in the above
snippet should be replaced with the following:
[sail_cSim]
pluginpath=/path/to/riscof/sail_cSim
docker=True
image=registry.gitlab.com/incoresemi/docker-images/compliance
The folder spike
contains various templates of files that would be required for testing of
any generic DUT. Components of this folder will need to be modified by the user as per the DUT spec.
By default the model_test.h
files and the link.ld
file will work out of the box for
spike
and sail
models.
Note
Custom DUTs can go through the various #TODO
comments to figure out what changes need to be
made in the respective python file.
The configuration of spike we will be using is available in the spike/spike_isa.yaml
. Modifying
this will change the tests applicable for the DUT. For now let’s leave it as is. For more
information on creating and modifying your plugins can be found in Building your Model Plugin
The sail_cSim
directory holds the plugin files for the reference SAIL model. Changes to any of
the files in this directory are typically not required (unless you know what you are doing).
We are now ready to run the architectural tests on the DUT via RISCOF.
Tip
By default RISCOF resorts to using RISC-V’s SAIL C Emulator as a reference model. To generate templates for a reference model add the argument ‘–refname myref’ to the setup command above. This will generate a myref directory containing template files for defining a reference model plugin. Lookout for the #TODO in the python file for places where changes will be required.
Tip
For details on the various configuration options supported by the sail_cSim plugin refer here.
3.7. Cloning the Architectural Tests¶
We will be running the tests from the official riscv-arch-test repository on the DUT and Reference models. To create a copy of the latest tests from the riscv-arch-test repository do the following:
$ riscof --verbose info arch-tests --clone
This will create a riscv-arch-test in the current working directory.
3.8. Running RISCOF¶
The RISCOF run is divided into three steps as shown in the overview Figure.
The first step is to check if the input yaml files are configured correctly. This step internally calls
the riscv-config
on both the isa and platform yaml files indicated in the config.ini
file.
riscof validateyaml --config=config.ini
This should print the following:
[INFO] : Reading configuration from: /scratch/git-repo/incoresemi/riscof/config.ini
[INFO] : Preparing Models
[INFO] : Input-ISA file
[INFO] : Loading input file: /scratch/git-repo/incoresemi/riscof/spike/sample_isa.yaml
[INFO] : Load Schema /home/neel/.pyenv/versions/3.7.0/envs/venv/lib/python3.7/site-packages/riscv_config/schemas/schema_isa.yaml
[INFO] : Initiating Validation
[INFO] : No Syntax errors in Input ISA Yaml. :)
[INFO] : Dumping out Normalized Checked YAML: /scratch/git-repo/incoresemi/riscof/riscof_work/sample_isa_checked.yaml
[INFO] : Input-Platform file
[INFO] : Loading input file: /scratch/git-repo/incoresemi/riscof/spike/sample_platform.yaml
[INFO] : Load Schema /home/neel/.pyenv/versions/3.7.0/envs/venv/lib/python3.7/site-packages/riscv_config/schemas/schema_platform.yaml
[INFO] : Initiating Validation
[INFO] : No Syntax errors in Input Platform Yaml. :)
[INFO] : Dumping out Normalized Checked YAML: /scratch/git-repo/incoresemi/riscof/riscof_work/sample_platform_checked.yaml
The next step is to generate the list of tests that need to be run on the models.
riscof testlist --config=config.ini --suite=riscv-arch-test/riscv-test-suite/ --env=riscv-arch-test/riscv-test-suite/env
This step calls the validate-step and thus the output adds one more line to the above dump:
[INFO] : Selecting Tests.
The tests are listed in the file: riscof_work/test_list.yaml
which should probably look
something similar to the following:
suite/rv32i_m/C/C-ADD.S:
work_dir: /scratch/git-repo/incoresemi/riscof/riscof_work/rv32i_m/C/C-ADD.S
macros: [TEST_CASE_1=True, XLEN=32]
isa: RV32IC
test_path: /home/neel/.pyenv/versions/3.7.0/envs/venv/lib/python3.7/site-packages/riscof/suite/rv32i_m/C/C-ADD.S
suite/rv32i_m/C/C-ADDI.S:
work_dir: /scratch/git-repo/incoresemi/riscof/riscof_work/rv32i_m/C/C-ADDI.S
macros: [TEST_CASE_1=True, XLEN=32]
isa: RV32IC
test_path: /home/neel/.pyenv/versions/3.7.0/envs/venv/lib/python3.7/site-packages/riscof/suite/rv32i_m/C/C-ADDI.S
suite/rv32i_m/C/C-ADDI16SP.S:
work_dir: /scratch/git-repo/incoresemi/riscof/riscof_work/rv32i_m/C/C-ADDI16SP.S
macros: [TEST_CASE_1=True, XLEN=32]
isa: RV32IC
...
...
...
The last step is to run the tests on the each of the models and compare the signature values to guarantee correctness.
riscof run --config=config.ini --suite=riscv-arch-test/riscv-test-suite/ --env=riscv-arch-test/riscv-test-suite/env
This should compile and execute the tests on each of the models and end up with the following log. The run will also open an HTML page with all the information.
...
...
