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 --recurse-submodules -cd riscv-wally -cd addins -cd riscv-isa-sim -*** replace these with a copy from ../install/F and ../install/D containing the Makefile.includes already updated -cp -r arch_test_target/spike/device/rv32i_m/I arch_test_target/spike/device/rv32i_m/F - -cp -r arch_test_target/spike/device/rv64i_m/I arch_test_target/spike/device/rv64i_m/D - -mkdir build -cd build -set RISCV=/cad/riscv/gcc/bin (or whatever your path is) -../configure --prefix=$RISCV -make (this will take a while to build SPIKE) -sudo make install -cd ../../riscv-arch-test -cp ../riscv-isa-sim/arch_test_target/spike/Makefile.include . -edit Makefile.include - change line with TARGETDIR to /home/harris/riscv-wally/addins/riscv-isa-sim/arch_test_target (or whatever your path is) - add line export RISCV_PREFIX = riscv64-unknown-elf- # this might not be needed if you have 32-bit versions of the riscv gcc compiler built separately -make -make XLEN=32 -exe2memfile.pl work/*/*/*.elf # converts ELF files to a format that can be read by Modelsim -cd ../../tests -cd imperas-riscv-tests -make -cd ../wally-riscv-arch-test -make -make XLEN=32 -exe2memfile.pl work/*/*/*.elf # converts ELF files to a format that can be read by Modelsim -cd ../linux-testgen/linux-testvectors -./tvLinker.sh -``` - -Notes: -Eventually download imperas-riscv-tests separately -Move our custom tests to another directory -Eventually replace exe2memfile.pl with objcopy +See Chapter 2 of draft book of how to install and compile tests.
