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.

To use Wally on Linux:

git clone https://github.com/davidharrishmc/riscv-wally
cd riscv-wally
cd imperas-riscv-tests
make
cd ../addins
git clone https://github.com/riscv-non-isa/riscv-arch-test
git clone https://github.com/riscv-software-src/riscv-isa-sim
cd riscv-isa-sim
mkdir build
cd build
set RISCV=/cad/riscv/gcc/bin   (or whatever your path is)
../configure --prefix=$RISCV
make
sudo make install

Notes: Eventually download imperas-riscv-tests separately Move our custom tests to another directory Handle exe2memfile separately.
