# RISCVBusiness Design documents and project information for the RISC-V Business project can be found here: [RISCV-Business Documentation](https://wiki.itap.purdue.edu/display/RISC/RISCV-Business) **Current User-Level ISA Spec :** v2.1 **Current Privileged ISA Spec :** v1.11 # Getting Started Getting started with RISCV Business consists of three steps: setting up the RISCV tool-chain, setting up the WAF build system, and finally interacting with the RISCV Business project itself. ## Generating RISC-V tool-chain Refer to the following link for instructions on installing the RISC-V software tools: [RISC-V Software Installation](https://riscv.org/software-tools/) Execute the following commands to download the correct version of the RISC-V tools: ~~~ git clone https://github.com/riscv/riscv-tools.git git checkout 4635ab67966c763a84f7217bc2c20b65dcabc7ec git submodule update --init --recursive ~~~ Change the line to build the riscv-gnu-toolchain tools to: ~~~ build_project riscv-gnu-toolchain --prefix=$RISCV --with-xlen="$with_xlen" --with-arch=RV32IM ~~~ Then run after setting the environment variable "RISCV" to your install location: ~~~ ./build.sh ~~~ ## Installing the build environment RISCVBusiness uses SoCFoundationFlow, built off of the waf build system. The following repository contains the source for waf: [SoCFoundationFlow](https://github.com/mattaw/SoCFoundationFlow) Refer to SoCFoundationFlow for installation instructions. ## Setup and Run RISCV Business First, clone the repository ~~~ git clone [email protected]:JakeStevens/RISCVBusiness.git ~~~ Once the directory is cloned, the configuration for a core must be generated before the project can be simulated/synthesized. This can be done using the example.yml configuration provided, or using a modification of that file. ~~~ ./scripts/config_core.py example.yml ~~~ Run the following command to run the regression test on RISCV-Business. All tests should pass: ~~~ ./run_tests.py ~~~ Refer to the LICENSE file for licensing information.
