Configurable RISC-V Processor
Wally is a 5-stage pipelined processor configurable to support all the standard RISC-V options, incluidng RV32/64, A, C, F, D, and M extensions, FENCE.I, and the various privileged modes and CSRs. It is written in SystemVerilog. It passes the RISC-V Arch Tests and Imperas tests. As of October 2021, it boots the first 10 million instructions of Buildroot Linux.
If you are new to using Linux and Github, follow the steps in the RISCV SoC Design textbook to:
See Chapter 2 of draft book of how to install and compile tests.
Download and install x2go - A.1
Download and install VSCode - A.4.2
Make sure you can log into Tera acceptly via x2go and via a terminal
Terminal on Mac, cmd on Windows, xterm on Linux
See A.1 about ssh -Y login from a terminal
Git started with Git configuration and authentication: B.1
Then follow Section 2.2.2 to clone the repo, source setup, make the tests and run regression
$ cd
$ export RISCV=/opt/riscv
$ git clone --recurse-submodules https://github.com/davidharrishmc/riscv-wally
$ cd riscv-wally
$ source ./setup.sh
$ make
$ cd pipelined/regression
$ ./regression-wally (depends on having Questa installed)
Add the following lines to your .bashrc or .bash_profile
if [ -f ~/riscv-wally/setup.sh ]; then
source ~/riscv-wally/setup.sh
